Title:
METHOD FOR CHECKING CONSISTENCY BETWEEN RADIOTHERAPY DEVICE ISOCENTER AND TREATMENT ISOCENTER
Document Type and Number:
WIPO Patent Application WO/2020/010842
Kind Code:
A1
Abstract:
A method for checking consistency between a radiotherapy device isocenter and a treatment isocenter, belonging to the technical field of radiotherapy. Said method comprises: acquiring projection data from a detector, and generating image data on the basis of the projection data; the image data comprises a light spot formed by a radiation beam generated by a treatment head of the radiotherapy device after being blocked by a radiation blocking body, and a shading located in the light spot (201); determining an offset between the radiotherapy device isocenter and the treatment isocenter on the basis of the image data (202). By using said method, the radiation blocking body is not affected by the radiation beam and does not need to be frequently replaced, and a process device can directly convert the projection data into image data without the participation of the staff. Therefore, said method simplifies the checking process, and further improves the checking efficiency.
