N2 - Radiotherapy is one of the important methods for the clinical treatment of tumors. A large number of tumor patients need to receive radiotherapy every year. However, radiation not only kills tumor cells but also causes damage to normal tissues during the treatment. To control the additional damage and ensure the treatment effect, it is necessary to verify and calibrate the absorbed dose of the patient. This paper proposes a new 3D dose reconstruction method based on EPID data, which can verify the radiation dose more accurately and quickly.Our method uses the idea of projection reconstruction and directly deduces the corresponding dose distribution from EPID data and CT images of the phantom. Experiments show that the method in this paper has short calculation time, good reconstruction accuracy, and high practicability.
