摘要:

我们提出了一种基于核乳胶膜探测器的质子成像的创新方法,该技术通过测量穿过患者身体的质子的位置和剩余范围来获得图像。为此目的,核乳胶膜交错与组织等效吸收剂,可以用来重建质子径迹具有非常高的精度。这是通过一个全自动的扫描程序,采用光学显微镜,经常用于中微子物理实验。质子射线照相术可用于质子治疗,以获得关于平均组织密度的直接信息,用于治疗计划优化,并以非常低的剂量对患者进行成像。基于核乳胶的探测器的第一个原型已经被构思、构造并用治疗质子束进行了测试。第一个有希望的实验结果已经通过成像简单的幻影。

英文摘要:

We propose an innovative method for proton radiography based on nuclear emulsion film detectors, a technique in which images are obtained by measuring the position and the residual range of protons passing through the patient's body. For this purpose, nuclear emulsion films interleaved with tissue equivalent absorbers can be used to reconstruct proton tracks with very high accuracy. This is performed through a fully automated scanning procedure employing optical microscopy, routinely used in neutrino physics experiments. Proton radiography can be used in proton therapy to obtain direct information on the average tissue density for treatment planning optimization and to perform imaging with very low dose to the patient. The first prototype of a nuclear emulsion based detector has been conceived, constructed and tested with a therapeutic proton beam. The first promising experimental results have been obtained by imaging simple phantoms.
