Title:
PARTICLE BEAM THERAPY SYSTEM, PARTICLE BEAM THERAPY SYSTEM CONSTRUCTION METHOD, AND PARTICLE BEAM THERAPY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/207937
Kind Code:
A1
Abstract:
Provided is a technique for constructing a particle beam therapy system that can improve an operation rate by shortening the construction period during which the therapy is interrupted. A particle beam therapy system (1) comprises a circular accelerator (3) for accelerating charged particles, a beam transport line for guiding the charged particles accelerated by the circular accelerator (3) to an irradiation chamber (18), a shielding wall (23) that is located around a radiation control area (16) in which the circular accelerator (3) and the beam transport line (4) are arranged and shields radiation originating from the circular accelerator (3) and the beam transport line (4), a specific part (34) that is provided at a position separating the outside of the shielding wall (23) from the radiation control area (16) and is capable of forming an additional opening of the irradiation chamber (19), and a blocking part (35) for blocking the specific part (34) and shielding the radiation passing through the specific part (34).
