PARTICLE BEAM TRANSPORT SYSTEM, AND SEGMENT THEREOF

摘要

The objective of the present invention is to provide a particle beam transport system which contributes to limiting the construction period and cost of a particle beam treatment facility provided with a plurality of treatment rooms each accommodating a particle beam irradiation device. This particle beam transport system 10 is characterized in being provided with: a main line 21 which transports to the outside a particle beam generated by an accelerator; branch lines 22 which branch from the main line 21; and irradiation devices 30 (30a to 30d) which are provided at the ends of the branch lines 22 and which irradiate patients with particle beams; and in that part or all of the main line 21 and the branch lines 22 consist of a plurality of segments 20, and the beam characteristics of the particle beams at both ends of each segment 20 are the same.
