Design optimization of a pixel-based range telescope for proton computed tomography

Proton Computed Tomography (proton CT) is an imaging modality able to measure the proton stopping power of the patient prior to treatment planning and treatment in proton therapy [1]. The goal of proton CT is to increase the accuracy of the proton range estimation, compared to conversion from the X-ray mass attenuation using X-ray CT [2]. Several design approaches for proton CT have been proposed. Usually, tracker planes in front of and behind the patient measure each proton ’s position and direction so that their path through the patient can be estimated [3,4].
