<p>PROBLEM TO BE SOLVED: To provide a radiotherapy system capable of performing radiotherapy accurately and efficiently, by avoiding adverse effects caused by large movement of a bed device and sharing the isocenter position between a radiotherapy apparatus and a medical imaging apparatus.SOLUTION: A radiotherapy system comprises: a radiotherapy apparatus 1 for performing medical treatment of a patient; a bed device 2 with a top board 2a to mount the patient during medical treatment by the radiotherapy apparatus 1; a medical imaging apparatus 3 which is disposed at a position opposite the radiotherapy apparatus 1 across the bed device 2, and which photographs the patient mounted on the bed device 2 to capture a medical image; and a control device 4 for controlling the radiotherapy apparatus 1 and the medical imaging apparatus 3. The medical imaging apparatus 3 is configured such that a facing surface to the radiotherapy apparatus 1 in the medical imaging apparatus 3 is movable to a position approaching a main body part 1b of the radiotherapy apparatus 1, beyond a facing surface to the medical imaging apparatus 3 in a radiation irradiation unit 1a of the radiotherapy apparatus 1.</p> |
