这项工作的长期目标是发展量化方法， 放射性示踪剂在人类和动物中的区域分布。 这将部分通过开发第三代 用于单光子发射计算机断层摄影的发生仪器 （SPECT），其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佳的图像重建 从数据中提取最大信息的技术， 包括衰减、散射和测量的校正 几何 此组件的重点是迭代、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.
