这项工作的长期目标是开发量化的方法 放射性标记示踪剂在人和动物体内的区域分布。 这部分是通过发展第三产业来实现的。 用于单光子发射计算机层析成像的生成仪器 (SPECT)接近灵敏度和分辨率的物理极限。 这项工作的第二个组成部分是设计最优图像重建 从数据中提取最大信息的技术，以及 包括衰减、散射和测量的校正 几何图形。这一部分的重点是迭代、离散 估计算法。
英文摘要
The long term goal of this work is the development of methods to quantify the regional distribution of radiolabeled tracers in humans and animals. This is to be accomplished in part through the development of third generation instruments for single photon emission computed tomography (SPECT) which approach the physical limits of sensitivity and resolution. A second component of this work is devising optimal image reconstruction techniques which extract the maximum information from the data and which include corrections for attenuation, scatter, and the measurement geometry. The emphasis in this component is on iterative, discrete estimation algorithms.
