摘要

级联核素通过中间状态连续发射两种或两种以上的伽马射线。级联伽马射线的重合检测在伽马射线成像中有几个优点。本文综述了双光子符合方法的三种应用。机械准直器双光子发射成像和康普顿双光子发射成像可以利用角分辨探测器识别放射源位置，减少核素间的串扰。此外，提出了一种新的康普顿重合成像方法，即对康普顿事件和光峰事件进行重合检测。虽然这种类型的巧合康普顿成像不能指定位置，但它在多核素康普顿成像中是有用的。

A double photon coincidence detection method for medical gamma-ray imaging

Cascade nuclides emit two or more gamma rays successively through an intermediate state. The coincidence detection of cascade gamma rays provides several advantages in gamma-ray imaging. In this review article, three applications of the double photon coincidence method are reviewed. Double-photon emission imaging with mechanical collimators and Compton double-photon emission imaging can identify radioactive source positions with their angular-resolving detectors, and reduce the crosstalk between nuclides. In addition, a novel method of coincidence Compton imaging is proposed by taking coincidence detection between a Compton event and a photopeak events. Although this type of coincidence Compton imaging cannot specify the location, it can be useful in multi-nuclide Compton imaging.
