  • wavelengths
  • The ultrasound has wavelengths only a few millimeters long which are much smaller than the source, and therefore naturally travel in an extremely narrow beam. (wikipedia.org)

  • Emergency ultrasound is used to quickly diagnose a limited set of injuries or pathologic conditions, specifically those where conventional diagnostic methods would either take too long or would introduce greater risk to a person (either by transporting the person away from the most closely monitored setting, or exposing them to ionizing radiation and/or intravenous contrast agents). (wikipedia.org)
  • Recent testing has shown that ultrasound can increase the effectiveness of cancer treatments such as chemotherapy and radiation therapy. (wikipedia.org)
  • nodes
  • The approach is using simple, inexpensive nodes (badges/tags) attached to the surface of persons, objects and devices, which then transmit an ultrasound signal to communicate their locations to microphone sensors. (wikipedia.org)
  • Breast ultrasound includes ultrasound of axillary tail of breast and sometime it includes ultrasound of axillae also to detect abnormal nodes in axilla because lymphatic drainage of parts of breast occur through axillary lymph nodes. (wikipedia.org)
  • tissue
  • There is little evidence that active ultrasound is more effective than placebo treatment for treating patients with pain or a range of musculoskeletal injuries, or for promoting soft tissue healing. (wikipedia.org)
  • Relatively high power ultrasound can break up stony deposits or tissue, accelerate the effect of drugs in a targeted area, assist in the measurement of the elastic properties of tissue, and can be used to sort cells or small particles for research. (wikipedia.org)
  • Ultrasound can ablate tumors or other tissue non-invasively. (wikipedia.org)
  • Ultrasound can be used as a guide when a needle is being inserted into the body to take a sample of tissue for a biopsy or to take a fluid sample as is done in amniocentesis, a test to detect abnormalities in the fetus. (womenshealthmag.com)
  • In summary, the primary risks associated with ultrasound would be the potential heating of tissue or cavitation. (wikipedia.org)
  • refers
  • 3D ultrasound refers specifically to the volume rendering of ultrasound data and is also referred to as 4D (3-spatial dimensions plus 1-time dimension) when it involves a series of 3D volumes collected over time. (wikipedia.org)
  • contrast agents
  • Contrast-enhanced ultrasound is regarded as safe in adults, comparable to the safety of MRI contrast agents , and better than radiocontrast agents used in contrast CT scans . (wikipedia.org)
  • bladder
  • Doctors order bladder ultrasounds when there's a concern about bladder problems, such as difficulty urinating or daytime wetting. (kidshealth.org)
  • A bladder ultrasound can show how much urine the bladder holds when it's full and whether someone completely empties the bladder when urinating. (kidshealth.org)
  • A bladder ultrasound is often done along with an ultrasound of the kidneys. (kidshealth.org)
  • Usually, you don't have to do anything special to prepare for a bladder ultrasound, although the doctor may ask that your child drink lots of fluids before the exam so that he or she arrives with a full bladder. (kidshealth.org)
  • The bladder ultrasound will be done in the radiology department of a hospital or in a radiology center. (kidshealth.org)
  • No risks are associated with a bladder ultrasound. (kidshealth.org)
  • Explaining in simple terms how the bladder ultrasound will be conducted and why it's being done can help ease any fear. (kidshealth.org)
  • If you have questions about the bladder ultrasound, speak with your doctor. (kidshealth.org)
  • If your pelvis is being scanned, you may have to drink several glasses of water beforehand so that your bladder is full, which provides better ultrasound images. (womenshealthmag.com)
  • acoustic
  • It uses a beam of ultrasound as a "virtual acoustic source", enabling control of sound distribution. (wikipedia.org)
  • While the anterior fontanelle is the most commonly used acoustic window for cranial ultrasounds, more advanced operators may gain adiditional views, especially of posterior fossa structures, by using the mastoid fontanelle, the posterior fontanelle and/or the temporal window. (wikipedia.org)
  • transducers
  • In November 2015, Philips launched a new era of portable ultrasound when it came out with the Lumify portable ultrasound machine, a first-of-its-kind portable ultrasound system that offers highly advanced transducers that connect via USB cable to off-the-shelf compatible Android devices. (wikipedia.org)
  • images
  • A radiologist (a doctor who's specially trained in reading and interpreting X-ray and ultrasound images) will interpret the ultrasound results and then give the information to your doctor, who will review the results with you. (kidshealth.org)
  • Automated whole-breast ultrasound (AWBU) is an ultrasound investigation of the breast that is largely independent of the operator skill and that allows the reconstruction of volumetric images of the breast. (wikipedia.org)
  • sound
  • The air within the beam behaves nonlinearly and extracts the modulation signal from the ultrasound, resulting in sound that can be heard only along the path of the beam, or that appears to radiate from any surface that the beam strikes. (wikipedia.org)
  • Gravis UltraSound or GUS is a sound card for the IBM PC compatible system platform, made by Canada-based Advanced Gravis Computer Technology Ltd. It was very popular in the demo scene during the 1990s. (wikipedia.org)
  • citation needed] The Gravis UltraSound was notable at the time of its 1992 launch by providing the IBM PC platform with sample-based music synthesis technology (marketed as "wavetable"), that is the ability to use real-world sound recordings rather than artificial computer-generated waveforms as the basis of a musical instrument. (wikipedia.org)
  • Released in 1996, the UltraSound Extreme is a 3rd party OEM system combining the UltraSound Classic with an ESS AudioDrive ES1688 sound chip for Sound Blaster Pro and AdLib emulation. (wikipedia.org)
  • It was found that the moths' responses vary according to ultrasound intensity, diving towards the ground if the pulse was of a high amplitude, or flying directly away from the sound source if the sound amplitude was low (if the sound was softer). (wikipedia.org)
  • Ultrasound energy, simply known as ultrasound, is a type of mechanical energy called sound characterized by vibrating or moving particles within a medium. (wikipedia.org)
  • Assessment
  • Contribution of ultrasound in the assessment of nerve disease. (wikipedia.org)
  • For those presenting with acute shortness of breath, ultrasound assessment of the lung, heart, and IVC can evaluate for potentially life-threatening diseases, including pneumothorax, significant pleural effusions, congestive heart failure, pulmonary edema, pericardial effusion, and some large pulmonary emboli. (wikipedia.org)
  • vessels
  • By using the converted heat energy that ultrasound provides, specific diseased tissues can be heated often to temperatures around 41° to 45°C. This increase in temperature has been linked to improved effectiveness of cancer treatment due to dilation of blood vessels and increased oxygen presence in affected tissues. (wikipedia.org)
