质子治疗是一种高度精确的癌症治疗形式，它需要准确地了解给患者提供的剂量，并验证患者的正确位置，以避免对关键的正常组织造成损害。质子计算机断层扫描(PCT)系统的发展是精确质子放射治疗计划的一个重要特征，因为它可以直接测量质子停止功率分布，提高剂量计算的精度，以及患者的位置。为了演示在质子治疗中心治疗期间根据临床需求获取射线和断层图像的能力，制造了一台PCT原型。
Proton therapy is a highly precise form of cancer treatment, which requires accurate knowledge of the dose delivered to the patient and verification of the correct patient position to avoid damage to critical normal tissues. The development of pCT (proton Computed Tomography) system represents an important feature for precise proton radiation treatment planning because it could permit the direct measurement of the proton stopping power distribution, improving the accuracy in dose calculus, and the patient's position. A pCT prototype was manufactured in order to demonstrate the capability to acquire, during treatments in proton therapy centers, radiographic and tomographic images according to clinical demands.
