Аннотация

Single-photon emission computed tomography (SPECT) is a diagnostic imaging technique in which radionuclide distribution tomograms are obtained using gamma photons detected at multiple label distribution sites. Emission computed tomography (ECT) allows obtaining a layer-by-layer distribution of functional properties from the upper and lower layers of the studied organ in biological tissues that do not take into account the contribution of radioactivity, and ECT images describing physiological and metabolic processes in the body and physiological and metabolic processes in the body are approximately 15 in SPECT systems With a spatial resolution of -20mm this is worse than TKT systems (1mm).
