  • 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.

  • 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)
  • 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)
  • detect

  • exclude
  • Suspected abdominal mass In suspected intussusception, an abdominal x-ray does not exclude intussusception but is useful in the differential diagnosis to exclude perforation or obstruction. (wikipedia.org)
  • Therefore
  • Abdominal x-ray is therefore not recommended for adults with acute abdominal pain presenting in the emergency department. (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)

  • 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)
  • distribution
  • 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)
