Three Dimensional Imaging of the Myocardium with Radionuclides

Abstract

Transverse sections of the distribution of 129Cs and and 201Tl in the human myocardium were obtained using 36 and 72 views of the thorax with a large field of view Anger camera. The cardiac cycle was divided into 100 ms intervals to obtain motion images of an average cycle of the beating heart. At least 300,000 events muscle be detected for each cardiac phase of each section for quantitative work. Over 8 million events from the upper thorax must be accumulated in gated studies if 3 or more sections are obtained for 8 intervals of 100-150 ms.
