To develop an X-ray detector capable of measuring radiation near the eye lens without obstructing the visual field of medical personnel during radiotherapy, we fabricated a 3×3 X-ray detector array on a PET substrate using pentacene thin films as the detection layer and CNT thin films as electrodes. The X-ray-induced currents measured by each detector were sequentially converted into dose rates, enabling real-time visualization of the 2D dose distribution. In this study, we present the device structure, measurement procedure, and results, and discuss its practical utility.
