Abstract

A charged particle therapy system is disclosed in which a hard switch for making a beam request of the accelerator side is installed in an irradiation room so that the accelerator side can start a desired beam irradiation preparation after depressing the hard switch. This arrangement allows the accelerator allocated time to be reduced, thereby improving the usage efficiency of the facilities by increasing the throughput with respect to patients.

Claims

1. A charged particle therapy apparatus comprising:

a plurality of irradiation rooms in each of which a therapy is performed by irradiating a person to be treated with accelerated charged particle beams,

wherein said apparatus is configured such that when a beam irradiation command requiring irradiation is issued after a beam request command requiring an irradiation preparation for charged particle beams has been issued, charged particle beams are applied to the person to be treated; and

wherein the plurality of irradiation rooms each have a switch for the beam request command.

2. The charged particle therapy apparatus according to claim 1, wherein the switch for beam irradiation command is disposed in an irradiation operation room.

3. The charged particle therapy apparatus according to claim 1 or 2, further comprising accelerator control means for uniquely determining an automatic operation setting file for an accelerator based on the beam request command.

4. The charged particle therapy apparatus according to any one of claims 1 to 3, wherein the particle is a proton.

5. A charged particle therapy system comprising:

a beam generator for generating charged particle beams;

an accelerator for accelerating the charged particle beams; and

a plurality of irradiation rooms in each of which a therapy is performed by irradiating a person to be treated with the accelerated charged particle beams,

wherein said system is configured such that when a beam irradiation command requiring irradiation is issued after a beam request command requiring an irradiation preparation for charged particle beams has been issued, charged particle beams are applied to the person to be treated; and

wherein the plurality of irradiation rooms each have a switch for the beam request command.
