摘要

背景:为了监测质子治疗中的质子束，一些研究小组正在开发快速伽马成像系统，这些系统有望提高治疗质量和患者安全。为了将提示伽马成像系统应用于点扫描质子治疗，该系统应该能够监测质子数量较少(<108个质子)的点的质子束范围，由于提示伽马统计数据不足，这通常是不可能的。

Improvement of Statistics in Proton Beam Range Measurement by Merging Prompt Gamma Distributions: A Preliminary Study

Background: To monitor proton beam in proton therapy, prompt gamma imaging systems are being developed by several research groups, and these systems are expected to improve the quality of the treatment and the patient safety. To apply the prompt gamma imaging systems into spot scanning proton therapy, the systems should be able to monitor the proton beam range of a spot with a small number of protons ( <108 protons), which is quite often not the case due to insufficient prompt gamma statistics.
