质子放射治疗已证明在某些癌症的治疗中有好处。为了充分优化这种治疗的递送,需要精确测量身体组织中的质子阻止能力。PRaVDA联盟正在开发一种新型的全固态设备来测量这些停止功率。PRaVDA测距望远镜(RT)使用一组24个CMOS有源像素传感器(APS)来测量患者术后的剩余质子能量。在这里,我们提出的CMOS传感器的能力,以检测信号大小的变化,质子穿越RT,比较结果与理论,并讨论这些结果对质子轨道重建的影响。
Proton radiotherapy has demonstrated benefits in the treatment of certain cancers. Accurate measurements of the proton stopping powers in body tissues are required in order to fully optimise the delivery of such treaments. The PRaVDA Consortium is developing a novel, fully solid state device to measure these stopping powers. The PRaVDA Range Telescope (RT), uses a stack of 24 CMOS Active Pixel Sensors (APS) to measure the residual proton energy after the patient. We present here the ability of the CMOS sensors to detect changes in the signal sizes as the proton traverses the RT, compare the results with theory, and discuss the implications of these results on the reconstruction of proton tracks.
