In the field of radiation therapy, the need for a flexible dosimeter that can be applied on the flexor surface for precise measurement of the surface dose is increasing. In particular, electron beam therapy has a shorter treatment depth than photon beam therapy; therefore, the surface dose must be measured accurately. This study investigates attenuation errors in a dosimeter. We demonstrated that the attenuation error depends on the thickness of the flexible functional materials, and it can serve as fundamental research for creating a flexible dosimeter that can be applied on the human body. The results indicated that the maximum attenuation error of a polyethylene terephthalate film with a thickness of 75 μm was 0.40% and 0.027% at 6 MeV and 9 MeV, respectively. Moreover, when using HgI 2 and PbI 2 as photoconductor materials, the maximum attenuation errors at 6 MeV were 1.35% and 1.67%, respectively. This study provides fundamental insights into dose errors ...

在电子束治疗中优化皮肤剂量计的衰减率误差评估

在放射治疗领域，对可施加在屈肌表面以精确测量表面剂量的柔性剂量计的需求正在增加。特别是，电子束疗法的治疗深度比光子束疗法短。因此，必须精确测量表面剂量。这项研究调查了剂量计中的衰减误差。我们证明了衰减误差取决于柔性功能材料的厚度，它可以作为创建可应用于人体的柔性剂量计的基础研究。结果表明，厚度为75μm的聚对苯二甲酸乙二酯薄膜在6 MeV和9 MeV下的最大衰减误差分别为0.40％和0.027％。此外，当使用HgI 2和PbI 2作为光电导体材料时，6 MeV时的最大衰减误差分别为1.35％和1.67％。这项研究提供了有关剂量误差的基本见解...
