Single photon emission computed tomography — (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera. However, it is able to provide true 3D information.… … Wikipedia
single-photon emission computed tomography — (SPECT) a type of tomography in which gamma photon–emitting radionuclides are administered to patients and then detected by one or more gamma cameras rotated around the patient. From the series of two dimensional images produced, a three… … Medical dictionary
Tomography — Basic principle of tomography: superposition free tomographic cross sections S1 and S2 compared with the projected image P Tomography refers to imaging by sections or sectioning, through the use of any kind of penetrating wave. A device used in… … Wikipedia
tomography — [tə mäg′rə fē] n. 〚< Gr tomos, a piece cut off (see TOMY) + GRAPHY〛 a process for producing an image of a single plane of an object excluding all other planes, as by using CT SCAN or ULTRASOUND, in … Universalium
tomography — Making of a radiographic image of a selected plane by means of reciprocal linear or curved motion of the x ray tube and film cassette; images of all other planes are blurred (“out of focus”) by being relatively displaced on the film. SYN:… … Medical dictionary
Positron emission tomography — (PET) is a nuclear medicine imaging technique which produces a three dimensional image or map of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron emitting radionuclide (tracer), which is… … Wikipedia

Network tomography — is the study of a network s internal characteristics using information derived from end point data. The word tomography is used to link the field, in concept, to other processes that infer the internal characteristics of an object from external… … Wikipedia
positronemission tomography — positron emission tomography n. Abbr. PET Tomography in which a computer generated image of a biological activity within the body is produced through the detection of gamma rays that are emitted when introduced radionuclides decay and release… … Universalium
positron emission tomography — (PET) tomography accomplished by detection of gamma rays emitted from tissues after administration of a natural biochemical substance (e.g., glucose, fatty acids) into which positron emitting isotopes have been incorporated. The paths of the… … Medical dictionary
