The possibility of using the nuclear scattering of 500-1000 MeV protons was investigated, in order to obtain direct, three-dimensional reconstruction of an object with only one exposure. The resolution should be about 1 mm3. Preliminary measurements with an incomplete set-up give a resolution of 10 mm3. Additional independent information on the relative concentration of hydrogen compared to other elements should also be obtainable by nuclear scattering radiography. The radiation doses involved are comparable to those of other techniques. The first experimental results are given.
为了仅通过一次曝光获得物体的直接三维重建，对使用500 - 1000兆电子伏特质子的核散射可能性进行了研究。分辨率应约为1立方毫米。使用不完整装置进行的初步测量给出的分辨率为10立方毫米。通过核散射射线照相术还应能够获得与其他元素相比氢的相对浓度的额外独立信息。所涉及的辐射剂量与其他技术相当。给出了首批实验结果。
