Title
(EN) Hit point positioning method of ray in scintillation crystal and system thereof
(ZH) 一种射线在闪烁晶体中的击中点定位方法及其系统
Abstract
(EN)
The invention, which relates to the technical field of nuclear detectors, provides a hit point positioning method of a ray in a scintillation crystal and a system thereof. A hit detector module is determined according to the total amplitude of signals received by all detector modules respectively; on the basis of a preset algorithm, the location of a reference hit point is calculated according tothe signal received by the hit detector module; when the location of the reference hit point is located in an internal area of the hit detector module, the location of the reference hit point is usedas the location of the hit point; and when the location of the reference hit point is located in an edge area of the hit detector module, the hit point is located again based on a preset algorithm byusing signals generated by the hit detector and the all slave detector modules. According to the invention, the positioning accuracy of the hit point of the ray in the scintillation crystal is improved.
