放射性同位素成像用于获取生物体内生化过程的信息，是一种日益重要的医学诊断工具。这些技术的改进和扩展取决于在若干领域取得的进展，例如放射性核素生产、放射性药物、辐射探测器和图像重建算法。本文仅就探测器技术进行综述，对医用放射性同位素成像仪器的现状进行综述，重点介绍用于乳腺X射线摄影和动物成像的高分辨率γ照相机和PET探测器系统的发展。目前的趋势是将联合收割机两种或两种以上的模式结合在一台机器上，以获得补充信息，也将予以考虑。(C)2004 Elsevier Ltd.保留所有权利。
Radioisotope imaging is used to obtain information on biochemical processes in living organisms, being a tool of increasing importance for medical diagnosis. The improvement and expansion of these techniques depend on the progress attained in several areas, such as radionuclide production, radiopharmaceuticals, radiation detectors and image reconstruction algorithms. This review paper will be concerned only with the detector technology.We will review in general terms the present status of medical radioisotope imaging instrumentation with the emphasis put on the developments of high-resolution gamma cameras and PET detector systems for scinti-mammography and animal imaging. The present trend to combine two or more modalities in a single machine in order to obtain complementary information will also be considered. (C) 2004 Elsevier Ltd. All rights reserved.
