Ischemic Heart Disease (IHD) poses an important diagnostic problem. Clinical picture of the disease is often atypical. SPECT is one of the main diagnostic tools in ischemic heart disease. Radioisotope study evaluates distribution of a radiopharmaceutical agent in the heart through a series of scintigraphic images taken by an external gamma camera. This article discusses the technical aspects of cardiac SPECT imaging, starting with a detection system, through image reconstruction, and ending with image filtering.
缺血性心脏病（IHD）带来了一个重要的诊断问题。该疾病的临床表现往往不典型。单光子发射计算机断层扫描（SPECT）是缺血性心脏病的主要诊断工具之一。放射性同位素研究通过外部伽马相机拍摄的一系列闪烁图像来评估放射性药物在心脏中的分布。本文讨论了心脏SPECT成像的技术方面，从检测系统开始，到图像重建，再到图像滤波结束。
