标题： Development of a proton Computed Tomography Detector System

摘要： 计算机断层扫描是成像人体内部异常组织的最有前途的新方法之一。 断层扫描也用于在放射治疗前准确放置患者。 用于治疗癌症的重粒子治疗已成为最有利和安全的选择之一。 为了充分利用重粒子治疗的优势，也需要使用重粒子进行摄影。 在本文中，我们介绍了质子计算机断层扫描系统的开发。 我们的第二代质子断层扫描系统由两个上游和两个下游跟踪器组成，这些跟踪器由纤维作为活性材料制成，以及一个由塑料闪烁体组成的范围探测器。 我们介绍了探测器系统、读出电子设备和数据采集系统的细节，以及整个系统的调试。 我们还介绍了范围探测器测试束的初步结果。 显示英文摘要

摘要： Computer tomography is one of the most promising new methods to image abnormal tissues inside the human body. Tomography is also used to position the patient accurately before radiation therapy. Hadron therapy for treating cancer has become one of the most advantageous and safe options. In order to fully utilize the advantages of hadron therapy, there is a necessity of performing radiography with hadrons as well. In this paper we present the development of a proton computed tomography system. Our second-generation proton tomography system consists of two upstream and two downstream trackers made up of fibers as active material and a range detector consisting of plastic scintillators. We present details of the detector system, readout electronics, and data acquisition system as well as the commissioning of the entire system. We also present preliminary results from the test beam of the range detector.
