In this study, the dose and mechanical accuracy in irradiation field for intensity modulated radiation therapy using the charge coupled device camera-organic phosphor with area type detector system was evaluated. The area type detector, which is made from plastic scintillator known as water equivalent material, and reflecting mirror were fabricated. Acquisitions of information such as stopping positions and moving distance related to multileaf collimator, and absorbed dose were able to obtain simultaneously with high precision easily. The system was achieved within the precision at clinical adaptive level, and the improvement of the quality assurance and more safely treatment were expected.

在这项研究中，评估了使用带有区域型探测器系统的电荷耦合器件相机-有机磷光体进行调强放射治疗的照射野的剂量和机械精度。制作了由水等效材料塑料闪烁体和反射镜制成的面型探测器。与多叶准直器相关的停止位置和移动距离以及吸收剂量等信息的获取能够轻松地以高精度同时获取。该系统达到了临床适应水平的精度，有望提高质量保证和更安全的治疗。
