Three-dimensional semiconductor detector array ArcCHECK for radiation detection and quality assurance of medical linear acceleration

Monitoring the radiation is an integral aspect of the physical practice of linear accelerators used in medical facilities to identify and treat radiation exposure. It is challenging for conventional two-dimensional dose test methodologies to meet the testing requirements of the volumetric modulated arc therapy (VMAT) irradiation technology. This study aimed to analyze multiple dose variations and mechanical correctness in linac operation using the ArcCHECK phantom and verify the accuracy of the method to improve the efficiency and precision of accelerator radiation monitoring.
