我们报告了质子计算机断层扫描和质子透射式放射成像在质子放射治疗的治疗计划和患者定位中应用的可行性研究的进展。我们分析了用具有很高空间和良好能量分辨率的硅探测器望远镜拍摄的中空铝柱的质子传输研究数据。此外，我们还探讨了在GEANT4模拟研究中对透射束的角发散角施加切割的有用性。
We report progress on a feasibility study of Proton Computed Tomography and Proton Transmission Radiography for applications in treatment planning and patient positioning for proton radiation therapy. We analyzed data from proton transmission studies through a hollow aluminum cylinder taken with a telescope of silicon detectors with very high spatial and good energy resolution. In addition, we explored the usefulness of applying a cut on the angular divergence of the transmitted beam in a GEANT4 simulation study.
