Rotating gantry for particle beam therapy equipment and winding method of linear member

摘要

PROBLEM TO BE SOLVED: To provide a rotary gantry for a particle beam therapy apparatus provided with a mechanism capable of easily exchanging a linear member drawn from a beam control device. A rotary gantry 10 includes a beam control device including a beam transport system 13 and an irradiation nozzle 14, a gantry skeleton 11, linear members 30, 40 drawn from the beam control device, a take-up spool 15, and an external device. There is. A beam control device is fixed to the gantry skeleton 11, and the gantry skeleton 11 is rotatable around the patient 18. The take-up spool 15 is provided on one end side of the gantry skeleton 11 with a common rotation axis with respect to the gantry skeleton 11, and a part of the linear members 30 and 40 is wound around the take-up spool 15. Will be done. Linear members 30 and 40 are connected to the external device. The rotary gantry 10 includes a first connection mechanism in which one end of the linear members 30 and 40 is detachable, and a second connection mechanism in which the other end of the linear members 30 and 40 is detachable to an external device. ..
