| 内容記述 | It is essential to consider large-angle scattered particles in dose calculation models for therapeutic ion beams. However, it is difficult to measure the small dose contribution from large-angle scattered particles. Therefore, we developed a parallel-plate ionization chamber consisting of concentric electrodes (ICCE) to efficiently and easily detect small contributions. The ICCE consists of two successive ICs with a common HV plate. The former is a large plane-parallel IC to measure dose distribution integrated over the whole plane, the latter is a 24-channel parallel-plate IC with concentric electrodes to derive the characteristic parameters describing the lateral beam spread. The aim of this study is to evaluate the performance of the ICCE. By taking advantage of the characteristic of ICCE, we studied the recombination associated with lateral beam profile. Also, we measured carbon pencil beam in several different media by using ICCE. As a result, we confirmed the ICCE could be used as a useful tool to determine the characterization of the therapeutic ion beams. | |||||
