| computed radiography | Radiography using a solid-state imaging device, such as a photostimulable phosphorplate, and recovering, enhancing, and displaying the image using a digital computer. (05 Mar 2000) |
| computed tomography | <investigation, procedure, radiology> A special radiographic technique that uses a computer to assimilate multiple X-ray images into a 2 dimentional cross-sectional image. This can reveal many soft tissue structures not shown by conventional radiography. Scans may also be dynamic in which a movement of a dye is tracked. Cuts may be 5 or 10 mm apart or, in some instances even further apart. A special dye material may be injected into the patients vein prior to the scan to help differentiate abnormal tissue and vasculature. The machine rotates 180 |
| helical computed tomography | <radiology> Computed tomography in which the X-ray tube continuously revolves around the patient, who is simultaneously moved longitudinally; computer interpolation allows reconstruction of standard transverse scans or images in any preferred plane. Synonym: helical computed tomography, helical CT, spiral CT. (20 Jun 2000) |
| X-ray computed tomography | <radiology> Tomography using X-ray transmission and a computer to reconstruct the image. See: computed tomography. (20 Jun 2000) |
| high resolution computed tomography | Computed tomography with narrow collimation to reduce volume-averaging and an edge-enhancing reconstruction algorithm to sharpen the image, sometimes with a restricted field of view to minimise the size of pixels in the region imaged; used particularly for lung imaging. Hypocycloidal tomography, body section radiography using a complex film and tube motion with a pattern resembling a three-leaf clover. (05 Mar 2000) |
| single photon emission computed tomography | <radiology> Tomographic imaging of metabolic and physiological functions in tissues, the image being formed by computer synthesis of photons of a single energy emitted by radionuclides administered in suitable form to the patient. The method uses radionuclides which emit a single photon of a given energy. The camera is then rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer then reconstructs the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the target area scanned. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as the size and volume of the organ. The disadvantage is that, unlike positron emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of available photons and hence degrades the image.

| spiral computed tomography | <radiology> Computed tomography in which the X-ray tube continuously revolves around the patient, who is simultaneously moved longitudinally; computer interpolation allows reconstruction of standard transverse scans or images in any preferred plane. Synonym: helical computed tomography, helical CT, spiral CT. (20 Jun 2000) |
| dynamic computed tomography | Computed tomography with rapid injection of contrast medium, usually with sequential scans at only one or a few levels; used to enhance the vascular compartment. Synonym: dynamic CT. (05 Mar 2000) |
| emission-computed tomography | <radiology> Tomography using emissions from radionuclides and a computer algorithm to reconstruct the image. (20 Jun 2000) |
