Problems solved by technology

[0005] However, in the system described in the above-mentioned Patent Document 1, each time an irradiation request of a high priority level is made, the distribution of an irradiation request of a low priority level is postponed, so sometimes it takes a long time for an irradiation request of a low priority level to be processed. time wai

Embodiment Construction

[0026] Hereinafter, preferred embodiments of the beam scheduler and beam allocation method according to the present invention will be described in detail with reference to the drawings.

[0027] Such as figure 1 and figure 2 As shown, the beam scheduler 1 according to the present embodiment is used in a particle beam irradiation facility 10 for treating cancer or the like by irradiating a tumor in a patient's body with a particle beam. The particle beam irradiation facility 10 has: a supply source 11 that generates beams such as proton beams, neutron beams, and carbon ion beams; a main control room 12 that is equipped with a main control unit 2 that controls the supply source 11; and four irradiation rooms A ~D, irradiation therapy with beams supplied from supply source 11 . In addition, the number of irradiation chambers of the particle beam irradiation facility 10 is not limited to four, and only two or more irradiation chambers may be provided.

[0028] The supply sourc...

Abstract

The invention discloses a beam scheduler and a beam distribution method of the beam scheduler. The invention aims to realize the effective utilization of a particle beam irradiation facility. When an irradiation request is received from one of a plurality of irradiation chambers (A-D) , the beam scheduler (1) in the invention adds maximum allowable waiting time at the end of beam distribution to the irradiation request, adds the irradiation request to the end of a waiting list, judges whether prediction waiting time at the end of distributing beam to one irradiation chamber is beyond the maximum allowable waiting time, brings forwardly the irradiation request in the waiting list when the prediction waiting time is beyond the maximum allowable waiting time, and distributes beam to the irradiation chamber corresponding to the highest-level irradiation request in the waiting list.

Description

technical field [0001] The present invention relates to a beam scheduler (beam scheduler) for managing beam distribution to a plurality of irradiation chambers in a particle beam irradiation facility and a beam scheduler's beam distribution method. Background technique [0002] As a technical document in this field, there is Japanese Patent Publication No. 2007-501084. This publication describes a system that automatically distributes particle beams to one of a plurality of irradiation chambers, and receives an irradiation request from the irradiation chamber in a state where no beam is distributed to any of the irradiation chambers. , the beam is distributed to the irradiation room that requests the irradiation. [0003] In addition, in this system, when irradiation requests are received in the state where beams have already been allocated in other irradiation rooms, the irradiation requests are arranged on the waiting list according to the preset priority order, and the b...
