  • A digital autopsy is a non-invasive autopsy in which digital imaging technology, such as with Computerized Tomography (CT) or Magnetic Resonance Imaging (MRI) scans, is used to develop three-dimensional images for a virtual exploration of a human body. (wikipedia.org)
  • The facility was supplied with £13 million worth of medical equipment by Toshiba Medical Systems Corporation, as part of their sponsorship with the club, and the medical centre is fitted with x-ray computed tomography (CT), magnetic resonance imaging (MRI) and ultrasound scanners, as well as other high-tech screening equipment normally reserved for hospitals.

  • radiation
  • Numerous X-ray beams and a set of electronic detectors rotate around the person, measuring the amount of radiation being absorbed throughout the body. (lungcancernewstoday.com)
  • Guidance is provided for Radiation Protection Advisers ( RPAs ) involved in the design of x-ray facilities and for RPAs , medical physicists and others involved in the acceptance/commissioning testing or routine performance evaluation of dental cone beam CT equipment. (www.gov.uk)
  • Current guidance for conventional x-ray equipment in these areas is not appropriate, and this report details the recommendations of the Health Protection Agency Working Party established to develop guidance on all aspects of radiation safety matters related to dental cone beam CT equipment. (www.gov.uk)
  • A computed tomography (CT) system comprises an X-ray radiation source to project a plurality of X-ray beams through an object and a detector array comprising a plurality of detector assemblies. (google.ca)
  • These characteristics lead to a high interaction probability for X-ray radiation. (wikipedia.org)
  • microscopic
  • Other tests such as chest X-ray (X-ray scanning of the chest) and sputum cytology (microscopic examination of the mucus coughed up from the lungs) usually are not recommended as screening tests because they do not meet the criteria of reducing the risk of dying from lung cancer. (lungcancernewstoday.com)
  • beam
  • Carbon-ion radiotherapy, a form of particle beam radiotherapy using accelerated carbon ions, offers more conformal and sharp dose distribution than X-ray radiotherapy. (biomedcentral.com)
  • Third, the X-ray beam originates anterior, at a shorter distance than recommended and quite often not tangentially to the diaphragmatic cupola, thereby hampering the correct interpretation of the silhouette sign. (biomedcentral.com)
  • At the same time, the examination table is moving through the scanner so that the X-ray beam follows a helical path. (lungcancernewstoday.com)
  • calcium
  • They arise from the cells along the pituitary stalk, specifically from nests of odontogenic (tooth-forming) epithelium within the suprasellar/diencephalic region and, therefore, contain deposits of calcium that are evident on an x-ray. (wikipedia.org)
  • visualize
  • Coronary catheterization uses pressure monitoring and blood sampling through a catheter inserted into the heart through blood vessels in the leg to determine the functioning of the heart, and, following injections of radiocontrast dye, uses X-ray fluoroscopy, typically at 30 frames per second, to visualize the position and volume of blood within the heart chambers and arteries. (wikipedia.org)
  • ADF-STEM tomography has recently been used to directly visualize the atomic structure of screw dislocations in nanoparticles. (wikipedia.org)
  • General
  • For acute abdominal pain in adults, an abdominal x-ray has a low sensitivity and accuracy in general, as well as for specific conditions such as gastrointestinal perforation, bowel obstruction, ingested foreign body, and ureteral stones. (wikipedia.org)
  • Therefore
  • Abdominal x-ray is therefore not recommended for adults with acute abdominal pain presenting in the emergency department. (wikipedia.org)
  • patient
  • Application- and patient size-dependent optimization of x-ray spectra for CT. (wikipedia.org)
  • October 1 - Godfrey Hounsfield's invention, X-ray computed tomography, is first used on a patient with a cerebral cyst at Atkinson Morley Hospital in Wimbledon, London. (wikipedia.org)
  • A patient with a history of allergy to x-ray dye may be advised to take special medication for 24 hours before CTA to lessen the risk of allergic reaction or to undergo a different exam that does not call for contrast material injection. (wikipedia.org)
  • data
  • Electron tomography is an extension of traditional transmission electron microscopy and uses a transmission electron microscope to collect the data. (wikipedia.org)
  • sample
  • The other disadvantage is the high X-ray damage to the sample. (wikipedia.org)
  • Another method of obtaining a tilt-series is the so-called conical tomography method, in which the sample is tilted, and then rotated a complete turn. (wikipedia.org)
  • equipment
  • In this test, special X-ray equipment is combined with sophisticated computers to produce multiple, cross-sectional images of the inside of the body. (lungcancernewstoday.com)
  • high
  • Because re-irradiation with X-ray radiotherapy may deliver high doses to a section of the bowels, carbon-ion radiotherapy was selected to treat the lymph node recurrences. (biomedcentral.com)
  • 8. The computed tomography system according to claim 6 , wherein the fins are attached to the spreader plate through adhesives of high conductivity and high bonding strength. (google.ca)
  • include
  • Coverage on the x-ray should include from the top of the Liver (or diaphragm) to the pubic symphysis. (wikipedia.org)
  • further
  • 5. The computed tomography system according to claim 1 , wherein the heat sink assembly further comprises at least one heat dissipation system to perform free convective thermal exchange with the thermal energy transformed from the spreader plate. (google.ca)
  • CTA should be avoided in patients with kidney disease or severe diabetes, because x-ray contrast material can further harm kidney function. (wikipedia.org)
