Abstract

A performance evaluation related to gamma-camera ectomography has been performed. It is noted that imaging of transversal sections of organs which occupy a large volume should preferably be performed with SPECT (single photon emission computed tomography). In imaging of longitudinal sections close to and parallel to the body surface, ectomography using a rotating slant hole collimator should be the tomographic method of choice. Ectomography may be applied in intensive care units using a mobile gamma camera to image the acutely ill myocardium and to evaluate treatment progress
