摘要： A radiation medical device, comprising a main support, and a radiation assembly (30) and an imaging assembly (20) respectively located at both ends of the main support. After an imaging scan is completed and pathological tissue positioning pictures are taken, a patient is directly moved to the other end of the main support to allow the radiation assembly (30) to perform radiation therapy to improve the efficiency of the radiation therapy after the completion of pathological tissue positioning, and effectively reduce movement of the patient when the patient is being moved for radiation therapy after the imaging assembly (20) completes pathological tissue positioning, thus reducing pathological tissue positioning error caused by too much movement.
