为了进行X射线照相系统的质量保证（QA）和质量控制（QC），我们使用不同形状和尺寸的散射体（如直径为2 cm的柱状碳棒），以15°、30°、45°、60°和75°的不同角度切割，研究了康普顿光谱。从多重散射最小、能量展宽和便于实际应用的角度研究了碳散射体的合适形状。我们的康普顿光谱使用两个散射计算的曝光结果证实了曝光测量使用校准电离室的结果。具有厚碳散射体的X射线照相系统的康普顿光谱被证明是用于评估这种系统性能的有用方法。
In order to perform quality assurance (QA) and quality control (QC) of the X-ray radiographic systems, we studied the Compton spectroscopy using different shape and size of scatterer such as columnar carbon rods of 2 cm diameter, which were cut at different angles of 15°, 30°, 45°, 60° and 75°. The appropriate shape of a carbon scatterer was studied in terms of minimum multiple scattering, the energy broadening and easy practical use. Calculated exposure results from our Compton spectroscopy using two scatteres were confirmed by the results of exposure measurement using a calibrated ionization chamber. The Compton spectroscopy of x-ray radiographic systems with a thick carbon scatterer proved to be a useful method for the evaluation of such system performance.
