Single photon emission computed tomography (SPECT) scanners using cadmium zinc telluride (CZT) offer compact, lightweight, and improved imaging capability over conventional NaI(Tl)-based SPECT scanners. The main purpose in this study is to propose a full-ring SPECT system design with eight large-area CZT detectors that can be used for a broad spectrum of SPECT radiopharmaceuticals and demonstrate the performance of our system in comparison to the reference conventional NaI(Tl)-based two-head Anger cameras.

使用大面积像素化 CZT 模块评估可变孔径全环 SPECT 系统：脑 SPECT 应用的模拟研究

与传统的基于 NaI(Tl) 的 SPECT 扫描仪相比，使用碲化镉锌 (CZT) 的单光子发射计算机断层扫描 (SPECT) 扫描仪提供了紧凑、轻便和改进的成像能力。本研究的主要目的是提出一种具有八个大面积 CZT 探测器的全环 SPECT 系统设计，可用于广谱 SPECT 放射性药物，并与参考传统 NaI(Tl ) 基于两头 Anger 相机。
