Transverse sections of the distribution of 129Cs and 201Ti 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-msec intervals to obtain motion images of an average cycle of the beating heart. At least 300,000 events must 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 three or more sections are obtained for 8 intervals of 100 msec to 150 msec.
使用大视野Anger相机对胸部进行36个和72个视角的拍摄，获得了人类心肌中¹²⁹Cs和²⁰¹Ti分布的横断面。心动周期被划分为100毫秒的间隔，以获取跳动心脏平均周期的运动图像。对于每个切片的每个心动周期阶段，进行定量研究时必须检测到至少300,000个事件。如果在100毫秒至150毫秒的8个间隔内获取三个或更多切片，则在门控研究中必须累积来自上胸部的超过800万个事件。
