FIELD: medicine.
SUBSTANCE: radioactive beam irradiation system comprises a beam irradiation device, a treatment plan module, a control module, a preparation room and an irradiation room, wherein the first stereoscopic vision device and the second stereoscopic vision device are located in the preparation room and the irradiation room, respectively. Simulated positioning is performed on the irradiated object in the preparation room in accordance with the position of the irradiated part determined in the treatment plan, and the first image of the irradiated portion obtained by the first stereoscopic vision device is compared with the treatment plan so as to determine the position of the simulated positioning; and performing the irradiation positioning on the irradiated object in the irradiation room in accordance with the determined position of the simulated positioning, and the second image of the irradiated portion obtained by the second stereoscopic vision device is compared with the treatment plan so that to control the beam irradiation device to start the radiation treatment on the irradiated object.
EFFECT: due to the presence of stereoscopic vision devices, it is ensured that the radiation treatment is performed on the irradiated object in accordance with the treatment plan, thereby obtaining the expected therapeutic effect, as well as reducing radiation damage to normal tissues.
