Computer-assisted spinal surgery is becoming more common; however, this is the first technical report to describe the technique of minimally invasive spinal posterior lumbar interbody fusion (MIS-PLIF) without using C-arm fluoroscopy. The authors report 2 years of follow-up of a 49-year-old female patient with L4 degenerative spondylolisthesis. The patient suffered from low back pain and intermittent claudication for more than 6 years. The authors performed computer-assisted MIS-PLIF without C-arm fluoroscopy. Instead, O-arm® navigation, the use of which reduces radiation exposure to patients as well as others in the operating room, was employed. Surgery was successful, and correct lumbar alignment was maintained. She had neither neurological deficits nor low back pain at her 12-month final follow-up. In conclusion, computer-assisted MIS-PLIF without C-arm fluoroscopy is a useful technique that reduces radiation exposure to the surgeon and operating room staff.

Spatial unsharp-mask processing and its variants are commonly used in x-ray radiography to enhance image contrast. We investigated the effect of three unsharp-masking filter kernels of different sizes on the detection of an advanced guidewire tip in simulated x-ray fluoroscopy image sequences. To isolate the effect of visual temporal processing, we repeated the experiments on single images. Filter gains were selected so that all three kernels increased the contrast of a 0.018-in. (0.457-mm) guidewire by a factor of 2 but had different effects on image noise and signal profiles. There was no statistically significant effect of unsharp masking on human-observer performance in single images. However, all three kernels significantly improved average performance in image sequences, and the guidewire contrast required for detection was reduced by 32%-40%. A prewhitening channelized observer model predicted the disparity between sequences and single images and fitted measurements at different kernel ...
Fluoroscopy is a test that uses a steady beam of X-ray to look at parts of the body and movement within the body, such as blood moving through a blood vessel. Fluoroscopy also can be used to help find a foreign object in the body, position a needle for a medical procedure, or realign a broken bone. A dye (contrast material) that shows up on fluoroscopy can be put in a vein (IV) or swallowed so vessels or organs show up clearly.. Fluoroscopy usually is done during other diagnostic procedures. For example, fluoroscopy is done during cardiac catheterization to look at the coronary arteries and the flow of blood through them. Fluoroscopy also may be used to look at the urinary tract or during a hysterosalpingogram to look at a womans reproductive organs.. Fluoroscopy uses more radiation than standard X-rays.. ...
Echocardiography is a potential alternative to X-ray fluoroscopy in cardiac catheterization given its richness in soft tissue information and its lack of ionizing radiation. However, its small field of view and acoustic artifacts make direct automatic segmentation of the catheters very challenging. In this study, a fast catheter segmentation framework for echocardiographic imaging guided by the segmentation of corresponding X-ray fluoroscopic imaging is proposed. The complete framework consists of: 1) catheter initialization in the first X-ray frame; 2) catheter tracking in the rest of the X-ray sequence; 3) fast registration of corresponding X-ray and ultrasound frames; and 4) catheter segmentation in ultrasound images guided by the results of both X-ray tracking and fast registration. The main contributions include: 1) a Kalman filter-based growing strategy with more clinical data evalution; 2) a SURF detector applied in a constrained search space for catheter segmentation in ultrasound images; 3) a

Atrial fibrillation (AFib), the most common arrhythmia, has been identified as a major cause of stroke. The current standard in interventional treatment of AFib is the pulmonary vein isolation (PVI). PVI is guided by fluoroscopy or non-fluoroscopic electro-anatomic mapping systems (EAMS). Either classic point-to-point radio-frequency (RF)- catheter ablation or so-called single-shot-devices like cryo-balloons are used to achieve electrically isolation of the pulmonary veins and the left atrium (LA). Fluoroscopy-based systems render overlay images from pre-operative 3-D data sets which are then merged with fluoroscopic imaging, thereby adding detailed 3-D information to conventional fluoroscopy. EAMS provide tracking and visualization of RF catheters by means of electro-magnetic tracking. Unfortunately, current navigation systems, fluoroscopy-based or EAMS, do not provide tools to localize and visualize single shot devices like cryo-balloon catheters in 3-D. We present a prototype software for ...

Chest fluoroscopy is a type of X-ray procedure used to assess the motion and function of the lungs and other structures of the respiratory tract.. Fluoroscopy is a study of moving body structures, similar to an X-ray "movie." A continuous X-ray beam is passed through the body part being examined. The beam is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail. Fluoroscopy, as an imaging tool, enables doctors to look at many body systems, including the skeletal, digestive, urinary, respiratory, and reproductive systems.. Chest fluoroscopy may be performed when the motion of the lungs, diaphragm (dome-shaped muscle that separates the abdominal cavity from the chest cavity), or other structures in the chest need to be evaluated. However, chest fluoroscopy involves a higher exposure to radiation than a standard chest X-ray, so its use is carefully considered.. Other related procedures that may be used to diagnose problems of the lungs and respiratory tract ...

Introduction: Fluoroscopic radiation exposure is a potential occupational health risk to the Hand Surgeon, given operator proximity and the relative lack of eye shielding. The association of eye radiation exposure and the early development of cataracts have been previously reported. Mini C-arm fluoroscopy is commonly utilized during routine Hand Surgery. At present, the amount of radiation exposure to the eye, associated with the routine use of mini C-arm fluoroscopy, is unknown, thus warranting further investigation. The purpose of this study is to test the hypothesis that eye radiation exposure, sustained during routine mini C-arm use, does not exceed that of previously reported critical radiation dosages to the eye.

Video-taped fluoroscopy was used in a research programme to review the characteristic attitudes of fetal limbs, head, neck and trunk, throughout the course of physiologically normal parturition in sheep. Nine fetuses from eight ewes were monitored during the whole process of natural birth by means of image-intensified X-ray fluoroscopy. All nine births were spontaneous and full term; with one exception they were unassisted. In all examinations the ewes were placed on their left sides on the X-ray table and lightly restrained with loose rope shackles. At parturition the ewes were fully conditioned to the examination procedure and had considerable limb mobility which allowed them to strain naturally during labour. No treatment was given to induce parturition or sedation. The consistency of observations was notable. A major finding was in the postural adaption of the forelimbs, taking the form of carpal extension with extreme flexion of the elbow and shoulder joints. This prepartum posture ...

Interventional fluoroscopy uses ionizing radiation to guide small instruments through blood vessels or other body pathways to sites of clinical interest. The technique represents a tremendous advantage over invasive surgical procedures, as it requires only a small incision, thus reducing the risk of infection and providing for shorter recovery times. The growing use and increasing complexity of interventional procedures, however, has resulted in public health concerns regarding radiation exposures, particularly with respect to localized skin dose. Tracking and documenting patient-specific skin and internal organ dose has been specifically identified for interventional fluoroscopy where extended irradiation times, multiple projections, and repeat procedures can lead to some of the largest doses encountered in radiology. Furthermore, in-procedure knowledge of localized skin doses can be of significant clinical importance to managing patient risk and in training radiology residents. In this ...
In 1974, after being assigned to the department of internal medicine at Kokura Memorial Hospital, Dr. Masakiyo Nobuyoshi* started to administer medical treatment focused on the circulatory system. Dr. Hideyuki Nosaka and Dr. Yukiyoshi Ito later joined Dr. Nobuyoshi, and established the Department of Cardiology in 1979. Catheter-based examinations began around this time, with PCIs beginning in 1981. According to Dr. Nobuyoshi, with the Department of Cardiology just established they were unable to procure an expensive angiography system, and instead performed cardiac catheterization using a Shimadzu gastric fluoroscopy system. This was apparently done because they were asked to perform cardiac catheterization by Dr. Toshihiko Ban* of the Department of Cardiovascular Surgery in order to perform bypass surgery. But they could not see any vessels using the gastric fluoroscopy system. I heard that because of this they carried out joint research with Shimadzu and improved the system into a cine film ...

The MediGuide Technology may provide significant benefits especially during longer interventions or examinations in the cath lab. The cardiologist no longer has to take fluoroscopic images of the patient each time the catheter is re-positioned, as is the case with current technology. As a result, less radiation and less contrast agent use is expected. "With the MediGuide Technology, we have expanded our CARE dose-reduction initiative with a critical functionality," said Dr. Heinrich Kolem, Head of the Angiography & Interventional X-ray business unit at Siemens Healthcare.. "We are convinced that our customers will achieve better clinical results, especially during complex procedures, and at the same time will be able to save both dose and time." The Heart Center Leipzig, Germany, has already performed the first interventions with Artis zee and the MediGuide Technology. "The low-radiation, precise localization of the catheter tip onto the pre-recorded fluoroscopy image is a most impressive ...

A stent or other intraluminal medical device having markers formed from housings integral with the stent and marker inserts having a higher radiopacity than the stent provides for more precise placement and post-procedural visualization in a vessel, by increasing the radiopacity of the stent under X-ray fluoroscopy. The housings are formed integral to the stent and the marker inserts are made from a material close in the galvanic series to the stent material and sized to substantially minimize the effect of galvanic corrosion. The housings are also shaped to minimize their impact on the overall profile of the stent.

In early 2012, the Lahey Clinic Medical Center (Burlington, MA, USA) cardiac catheterization laboratory reduced its standard pulse rates for both fluoroscopy and CINE-acquisition from 15 to 10 frames per second (FPS). To assess the effect of this on radiation dosing and image quality, the authors conducted a retrospective review of 524 coronary procedures (both diagnostic and interventional) conducted over a 3-month period from June to August 2011 (Standard dose cohort) and compared these with 491 cases conducted over the same period in 2012 (Reduced dose cohort). The primary outcome measure was the total x-ray dose in air kerma (mGy), with secondary measures of fluoroscopy time and contrast use. In a sub-study to assess the effect of reduced CINE-acquisition frame rates on study quality, 53 studies from each cohort were matched for clinical variables and then subjected to retrospective blinded review by 5 interventional cardiologists (each reviewed 18 cases). A semi-quantitative scale (from 1 ...
In recent years, using the ionizing radiation in the interventional cardiology has been increased; this is because of the rapid growth of the number of interventional procedures and the high levels of radiation dose in these examinations. Therefore, it is necessary to develop procedures for managing the use of fluoroscopy radiation to ensure that patients and personnel are not exposed to excessive levels of radiation. It seems that by the new generation devices of fluoroscopy that are equipped with a real dosimeters or dose area product (DAP)-meter which are able to record the produced dose rate in the area of patients body in each procedure, it is possible to calculate the cardiologist dose with simulation ...

You may be offered a sedative before the test to help you relax. You sit in a special chair or on an x-ray table. The health care provider cleans your feet, and then injects a small amount of blue dye into the area (called webbing) between your toes. Thin, bluish lines appear on the top of the foot within 15 minutes. These lines identify the lymph channels. The health care provider numbs the area, makes a small surgical cut near one of the larger blue lines, and inserts a thin flexible tube into a lymph channel. This is done on each foot. Dye (contrast medium) flows through the tube very slowly, over a period of 60 to 90 minutes. A special x-ray machine, called a fluoroscope, projects the images on a TV monitor. The health care provider uses the images to follow the dye as it spreads through the lymphatic system up your legs, groin, and along the back of the abdominal cavity. Once the dye is completely injected, the catheter is removed and stitches are used to close the surgical cut. The area is ...

You may want to ask your doctor about the amount of radiation used during the procedure and the risks related to your particular situation. It is a good idea to keep a record of your past history of radiation exposure, such as previous scans and other types of X-rays, so that you can inform your doctor. Risks associated with radiation exposure may be related to the cumulative number of X-ray examinations and/or treatments over a long period of time.. If you are pregnant or suspect that you may be pregnant, you should notify your doctor. Radiation exposure during pregnancy may lead to birth defects.. If contrast dye is used, there is a risk for allergic reaction to the dye. Patients who are allergic to or sensitive to medications, contrast media, iodine, or latex should notify their doctor. Also, patients with kidney failure or other kidney problems should notify their doctor.. There may be other risks depending on your specific medical condition. Be sure to discuss any concerns with your doctor ...

Purpose: The purpose of this study was to demonstrate the efficacy of the digital fluoroscopy system (DFS) for the in vivo assessment of pharmacologically induced posterior vitreous detachment (PVD) and vitreous liquefaction in a rabbit model. Methods: Twenty eyes from 10 New Zealand white rabbits were divided into 5 groups. In each group, one rabbit received an intravitreal injection of 2.0 U plasmin in the right eye and 0.5 U plasmin in the left eye. Intravitreal injection of 0.1 mL balanced salt solution (BSS) was given in the right eye, and no injection was given in the left eye of another rabbit used as a control. Intraocular fluid dynamics were assessed by the DFS, using a contrast agent in each group at different time intervals (6 hours, 12 hours, 1 day, 3 days, and 7 days). After rabbits were killed, both eyes were enucleated. Scanning electron microscopy was used to confirm the morphological alterations of the vitreoretinal interface as observed in the DFS. Results: Complete PVD was ...
Introduction Trigeminal neuralgia (TN) is characterized by episodes of shooting pain in the areas innervated by one or more divisions of the trigeminal nerve. The initial treatment of TN is with drugs but the increased frequency and intensity of the neuralgic episodes often force the patient to seek alternative therapies. Microvascular decompression (MVD) and radiofrequency thermal lesioning of trigeminal rootlets (RFTR) offer close to the best results for TN. MVD has the disadvantage of being an open surgical procedure with its attendant risks and longer hospital stay, whereas RFTR is a short, day-care procedure. However this latter procedure involves positioning of the RF needle in the area behind the trigeminal ganglion through the foramen ovale, which can pose significant challenges. ...

0031] Since the adaptive learning is a greedy method, it needs a good starting point to converge to a good solution. The starting point can be the discriminant learned offline from collected training samples, denoted as A.sup.(0). Even if the initial discriminant does not fit the current environment, the adaptive learning can quickly converge to a good solution. FIG. 4 illustrates an example of adaptive discriminant learning for detection of a pigtail catheter in a fluoroscopic image sequence. In the example of FIG. 4, the pigtail catheter appears as almost a line and the initial discriminant model has a large error of above 40%. During tracking, A is updated at each frame based on the tracked results (or the initialization at the first frame) as positive samples and image patches away from the tracked objects as negative samples. Image (a) of FIG. 4 shows positive samples 402 and negative samples 404 extracted from a frame of a fluoroscopic image sequence. In a possible implementation, the ...

A contrast dye is injected to identify the area to be injected and then with the aid of a fluoroscope (a type of x-ray machine) to guide the needle, the medications are injected into the area around the plexus. Often a preliminary injection of local anesthetic will be used to determine if the patient will benefit from a superior hypogastric plexus block, if it is determined that the procedure will be effective a more permanent analgesic will be injected (such as phenol). After the procedure has been completed the patient will be placed in an observation area to watch for an allergic reaction to the medications. ...

Within the field of minimally invasive surgery where an excellent image guidance is of the utmost importance, todays most popular imaging modalities are x-ray fluoroscopy, ultrasound, and optical endoscopy. The use of MRI however includes a variety of clinical benefits ranging from a good soft tissue contrast and a superior lesion sensitivity to patient-safe non-radiation qualitative imaging. The AMIT researchers want to promote the application of MRI in minimally invasive procedures by overcoming the typical weaknesses in this powerful imaging modality. As a result, the AMIT team aims to design innovative tools for accurate, reliable instrument tracking and for adequate visualisation, as well as to develop an interactive and intuitive user interface and to use preoperative images together with intra-operative real time visual data.. In fact, MRI is not a real time imaging method. It is possible to obtain images within one second but often a much longer scanning time is needed in order to ...

Conclusion To investigate CD, our analysis suggests that fluoroscopy should be used initially and only if negative and clinical suspicion of CD remains should CE then be done. The very low diagnostic yield for fluoroscopy vs. CE for MGIH demands that CE should be the imaging modality of choice and fluoroscopy abandoned as a diagnostic option. To determine the place for new, often expensive, investigation techniques cost minimisation analysis is effective. We estimate that, for our patient cohort, the use of CE as the first investigation for MGIH and only after a negative fluoroscopy study for suspected CD, our institution could have saved ∼£7000. Extrapolating these figures nationally the judicious use of CE has the potential to save the NHS £1.3 million per annum. The analysis does not factor in other CE benefits such as faster diagnosis of MGIH and less radiation exposure. ...
Atherosclerosis is a disease in which accumulation of plaque in the walls of the artery restrains the flow of oxygen-rich blood and appropriate feeding of organs . Intravascular imaging techniques, such as intravascular ultrasound (IVUS) and intravascular optical coherence tomography (IVOCT) , have been applied as techniques with resolutions superior to X-ray fluoroscopy to visualize the artery walls and plaques. Some clinician have proposed the use of IVUS and IVOCT to verify the results of
We will do everything we can to make you comfortable. You will lie on a table or stand up, depending on the area being x-rayed, and the camera will be set above or in front of you in order to get the correct angle. Fluoroscopy takes anywhere from a few minutes to an hour, depending on its purpose.. For gastrointestinal (GI) studies you will usually need to drink a barium contrast agent or have a barium enema. The barium helps create a clear image that shows any polyps and other abnormalities. After a barium procedure your stool may turn a grayish white, but this is normal. Drink a lot of liquids to flush the barium out because it might cause constipation.. ...
TY - JOUR. T1 - MO‐D‐ValB‐08. T2 - Fluoroscopic Tracking of Lung Tumor Mass Without Implanted Fiducial Markers. AU - Cui, Y.. AU - dy, J.. AU - Sharp, G.. AU - Alexander, B.. AU - Jiang, S.. PY - 2006. Y1 - 2006. N2 - Purpose: To develop techniques for direct lung tumor tracking in fluoroscopic images without implanted markers. Method and Materials: During the patient setup session, a pair of 15 second orthogonal fluoroscopic images are taken and processed off‐line to generate reference templates. Each breathing cycle is divided into 12 phase bins. Setup image frames falling in a specific bin are motion‐enhanced and averaged, and an ROI that contains the tumor is selected to be the reference template for that phase bin. Each reference template corresponds to a tumor position in the image. During the treatment, as soon as a fluoroscopic image is acquired, the cross‐correlation score between each reference template and this image is maximized by allowing small shifts of the template in ...
본 증례는 좌측 복부 통증으로 내원한 55세 남자로서, 배설성요로조영술상 좌측 상부요관협착으로 진단되어 6개월간 매달 double-J 스텐트를 교체해오던 환자였다. 환자는 비만과 당뇨, 고혈압, 심근경색의 병력으로 인해 마취 위험도가 높아 요관부목 교체 시마다 입원 치료가 필요하였다. 환자가 영구적 요관부목 설치에 동의하여 척추마취하에 Memokath 051 (Engineers & Doctors, Copenhagen, Denmark)를 유치하였다. 수술 전 검사에서 혈청 크레아티닌치가 1.7 mg/dL로 증가된 것 외에는 일반혈액검사, 생화학검사 및 소변검사결과는 정상 범주였다. 배설성요로조영술상 좌측 상부요관에 2 cm 이상의 협착이 보여 C-arm fluoroscopy로 협착의 위치를 확인하면서 Memokath를 성공적으로 유치하였다(Figs. 1, 2). 수술 후 3일째 환자는 갑작스런 좌측 복부 통증을 호소하였고, 다시 시행한 ...
Genicular nerve blocks can be performed under fluoroscopic or ultrasound guidance. Nerves are targeted adjacent to the periosteum on the medial aspect of the tibia, and at both the medial and lateral aspects of the femur at the junctions of the shaft and the epicondyle.. Under fluoroscopic guidance, we approach the target by introducing a spinal needle from either an anteroposterior or lateral entry point with the final position residing adjacent to the bone. After negative aspiration, some physicians elect to administer contrast to exclude vascular uptake, avoiding a false negative result. To conclude the procedure, 2 mL of local anesthetic is deposited on each of the superolateral, superomedial and inferomedial genicular nerves.. While GNRFA performed under fluoroscopic-guided requires a procedure room, the ultrasound-guided procedure can be performed conveniently in the outpatient clinic setting without radiation exposure. In addition, two recent studies suggest ultrasound guidance improves ...

A coil electrode for use in an electrophysiology probe includes a first material having a relatively high radiopacity and a second material having a relatively high resiliency. This combination provides the necessary levels of durability, resiliency and radiopacity. An electrophysiological probe includes a support structure, at least one first electrode defining a first radiopacity supported on the support structure and at least one second electrode defining a second radiopacity supported on the support structure, the second radiopacity being greater than the first radiopacity. When viewed under a fluoroscope, the pattern of electrodes of varying radiopacities allows the physician to distinguish between individual electrodes.
An endocardial electrode assembly of three or more spring legs to be inserted into the heart, sets of electrodes on respective spring legs comprising distinctive geometrical patterns, over the ventricle-contacting span of the legs, such that the active sets of electrodes provide recognizable patterns when within a ventricle of the heart and viewed with a fluoroscope, the respective locations of at least some of the electrodes of these patterns being staggered relative to electrodes on other legs in the manner to reduce lateral clumping, thus to permit the numerous electrodes to be housed in a catheter sized to be conveniently introduced into the heart.
The researchers tested the platform-the AlluraClarity from Philips Healthcare of Best, The Netherlands-on 52 patients and compared radiation exposure and image quality with results from 26 other patients who had undergone similar procedures on an older system. Radiation exposure, including air kerma (AK), the radiation exposure in free air before reaching the body, and dose area product (DAP), the absorbed radiation dose multiplied by the area irradiated, was recorded throughout the procedure. The new system resulted in an exposure reduction in total AK and DAP of 58 percent and 60 percent, respectively, compared to the old platform. DAP for fluoroscopy, DSA and CBCT decreased by up to 66 percent, 79 percent and 14 percent, respectively. During the procedures, no relevant problems due to image quality were reported. Likewise, the blinded evaluation of image quality revealed no differences between the new and the old imaging platforms. Both patient cohorts showed no difference with regard to body ...

Mammograms are fixed plate x rays that are designed to locate tumors within the breasts. Dental x rays are designed to locate decay within the tooth. Sometimes a liquid called contrast material (for example, barium) is used to help outline internal organs such as the intestines. The contrast material absorbs x rays, helping to make soft tissue more easily visible on the x-ray films. Contrast material is commonly used in making x rays of the digestive system. The contrast liquid can be swallowed or injected, depending on the part of the body being x rayed. This may cause some minor discomfort. Fluoroscopy is a special x-ray technique that produces real-time images on a television monitor. With fluoroscopy, contrast material is injected into a blood vessel. The physician can then watch the real-time movement of the contrast material to determine if there are blockages in circulation. Fluoroscopy is also used to help guide catheters into place in the heart during cardiac catheterization or to guide ...
Intraoperative localization in spinal surgery is essential to facilitate the best surgical outcome and to avoid wrong-site surgery. Intraoperative fluoroscopy is generally adequate, but anatomical variation, body habitus, and the inherent difficulties of fluoroscopy at certain levels may lead the surgeon astray. Here, the authors present their technique for preoperative localization that relies solely on fixed anatomical landmarks using CT-guided, percutaneously placed radiopaque markers. In the outpatient setting, low-dose CT scanning of the neuraxis is performed to identify fixed landmarks and, under local anesthesia and CT guidance, a pushable microcoil is inserted through a Chiba needle into the periosteum of the pedicle at the level of interest. The patient returns home with no precautions while the coil is in situ, and then the patient returns sometime later for surgery. Intraoperatively, typically a single lateral radiograph is required to visualize the coil and the level. Preoperative ...

According to the American Academy of Pain Medicine, several professional medical associations, including the American Society of Anesthesiologists (ASA) and the AAPM, began working with CMS to address concerns about potentially misvalued codes back in 2012.. According to the ASA, CMS initially attempted to re-value codes 62310-62311 and 62318-62319 through drastic reductions of the wRVUs for 2014. The cohort of specialties appealed to CMS to revert back to the original work values for 2015, and while CMS agreed, they would no longer allow separate reporting of any associated imaging, such as code 77003 for fluoroscopic guidance.. Under the new coding scheme, physicians still are not allowed to report codes 77003, 77012, 76942 or any other guidance codes in addition to epidural injections. However, they can choose from codes 62321, 62323, 62325, and 62327 that include the imaging as reflected in the increased wRVUS.. What does this mean for code selection?. ...
ERCP is a specialized endoscopic procedure that is performed with fluoroscopy and contrast injection to examine and treat conditions of the bile ducts and pancreas, such as removing gallstones, opening obstructed bile ducts, and obtaining biopsies in suspected tumors. Conventional ERCP is hindered by the flat, two-dimensional, black and white image rendered by fluoroscopy, which can make it difficult to determine where to obtain tissue samples and potentially lead to an inaccurate or inconclusive clinical diagnosis. As a result, gastrointestinal endoscopists may need to conduct additional testing or even repeat the entire ERCP procedure. Data shows that up to 30 percent of diagnostic ERCPs are inconclusive, potentially creating the need for additional testing ...

These effects can result whenever long fluoroscopic times are used during interventional procedures, such as coronary angioplasty, stent placement, radiofrequency cardiac ablation and vascular embolization. "With the equipment that currently is being used, the physician can minimize the chance for burns by moving the X-ray source instead of keeping the intensity on one spot," explained Darold Wobschall, Ph.D., UB professor emeritus of electrical engineering and president of Esensors. "The problem is that the physician is concentrating on the surgery and with X-rays coming in, he or she would have to be keeping mental track of where the dose is occurring at the same time." "Our system solves that problem," said Wobschall ...

In endovascular interventions, thin, flexible instruments are inserted through the skin into the blood vessels to diagnose and treat various diseases of the vascular system. One drawback is that the instruments are difficult to maneuver in the desired direction due to limitations in shape and flexibility. Another disadvantage is that the interventions are performed under intermittent fluoroscopy/angiography imaging. Magnetic resonance imaging (MRI) may offer advantages over X-ray guidance. It presents a good soft tissue contrast without the use of nephrotoxic media or ionizing radiation. The aim of this study is to develop a guidewire that is compatible with MRI and includes a steerable segment at the tip. This added degree-of-freedom may improve the maneuverability of the devices thereby the efficiently and safety of the navigation. A 1.6 m (5 ft, 3 in.) long and 0.035 in. diameter guidewire that consists of MR compatible materials and has a flexible tip was designed. The only metallic part was ...
