质子在寿命结束时储存了大部分能量，其特征是出现布拉格峰。这使得质子治疗成为一种可行的方法来靶向癌症组织，同时将对周围健康组织的损害降至最低。然而，为了利用这种高精度的治疗，肿瘤成像需要更高的精度。在目前的质子治疗实践中，由于X射线和质子阻止能力之间的转换，存在大约±3%的不确定度。利用质子的成像系统有可能消除这种不准确。这项研究的重点是开发一种用高密度玻璃闪烁体构建的概念验证质子成像探测器。
Protons deposit the majority of their energy at the end of their lifetimes, characterized by a Bragg peak. This makes proton therapy a viable way to target cancerous tissue while minimizing damage to surrounding healthy tissue. However, in order to utilize this high precision treatment, greater accuracy in tumor imaging is needed. An approximate uncertainty of ±3% exists in the current practice of proton therapy due to conversions between x-ray and proton stopping power. An imaging system utilizing protons has the potential to eliminate that inaccuracy. This study focuses on developing a proof of concept proton-imaging detector built with a high-density glass scintillator.
