The use of tracers with high radioactivity in rapid dynamic quantitative studies (such as radioisotope angiocardiography), performed by the Anger-camera and data-processor, makes it possible to obtain a high counting ratemfor correct interpretation of the results of the analysis of activity/time curves in regions of interest, the authors determined, under different working conditions, the deadtimes of two Anger-cameras (Pho-gamma HP and Radicamera II), both connected to a data-processing system (Med-II). The problems inherent in this determination are analyzed and discussed. A computer program for curve correction was written and some examples of applications of it are presented, including an experiment to test the accuracy of the correction.
在由安格相机和数据处理器进行的快速动态定量研究（如放射性同位素心血管造影）中，使用高放射性示踪剂能够获得高计数率，以便正确解释感兴趣区域内活性/时间曲线的分析结果。作者在不同工作条件下，测定了两台与数据处理系统（Med-II）相连的安格相机（Pho-gamma HP和Radicamera II）的死时间。分析并讨论了该测定中固有的问题。编写了用于曲线校正的计算机程序，并给出了一些应用实例，包括一项测试校正准确性的实验。
