The quasi-elastic scattering of 1 GeV protons permits the three-dimensional reconstruction of the density distribution in extended bodies. Fast multiwire proportional chambers are used to localize the position of every incoming and outgoing charged particle and to determine the coordinates at the interaction vertex. This article describes tests on a human head fixed on formalin. The comparison with computed tomography scans and anatomical sections is encouraging. Slices with a volume element of 5.5 mm3 illustrate the sensitivity of the method. The results also demonstrate the ability of the method to select the density distribution of hydrogen by making use of the kinematic relations specific to elastic scattering. Trials of this method in living humans are being planned.
1吉电子伏质子的准弹性散射能够对延展物体内的密度分布进行三维重建。快速多丝正比室用于确定每个入射和出射带电粒子的位置，并确定相互作用顶点处的坐标。本文描述了对固定在福尔马林中的人头进行的测试。与计算机断层扫描和解剖切片的比较结果令人鼓舞。体积元为5.5立方毫米的切片说明了该方法的灵敏度。结果还证明了该方法通过利用弹性散射特有的运动学关系来选择氢密度分布的能力。正在计划在活人身上进行该方法的试验。
