Attention has been paid. As a recent irradiation method for particle beam therapy, a minimal irradiation point (spot) is painted in a two-dimensional direction, and the energy and range shifter of the accelerator are changed to superimpose layers (slices) in the depth direction to the affected area.

If an unexpected failure occurs in the control device during irradiation, the computer does not know the end of irradiation, so the irradiation execution record is not stored in the database. If the irradiation record is not saved, it is difficult to know how much dose was given to the affected area, and from which spot the remaining dose should be irradiated. Therefore, conventionally, necessary information was collected from the screen display of the computer, the irradiation execution record (irradiation dose, interrupted slice number, interrupted spot number, spot count, etc.) was calculated manually, and the irradiation execution record of the calculation result was directly recorded. The irradiation execution record was recovered by manually writing in the database.

In addition, in case of failure, for example, in Patent Literature 1, information is stored in a memory in the dose monitor by using a particle beam therapy apparatus that switches the role of the main and sub two dose monitors for each irradiation. Is disclosed.

Embodiment 1.
1 is a diagram showing a configuration of a particle beam therapy system according to a first embodiment of the present invention. As shown in FIG. 1, the accelerator 1 and the treatment room 3 constitute the particle beam therapy system 100 of the first embodiment. Beam emission from the accelerator 1 is controlled by a beam control device (not shown). A patient 31 as an irradiation target and an irradiation device 32 exist in the treatment room 3, and the irradiation device 32 is controlled by the irradiation control device 51. The recovery system 5 is a component that constitutes the irradiation device 32.

The recovery system 5 includes an irradiation control device 51, a dose monitor 52, an irradiation execution record generation device 53, and a database 54. The irradiation control device 51 controls irradiation of the beam by the irradiation device 32 in the treatment room 3. The dose monitor 52 measures the dose of the beam emitted from the irradiation device 32 and stores the irradiation progress as an irradiation log A1. The irradiation execution record generation device 53 connects the display device 55 that functions as a terminal operated by the user, and acquires the irradiation log A1 from the dose monitor 52 according to an instruction from the outside. The irradiation execution record generation device 53 performs totalization and calculation according to the acquired irradiation log A1, and generates an irradiation execution record B1. The database 54 stores the irradiation execution record B1 recovered by the irradiation execution record generation device 53.

Next, basic operations of the accelerator 1 and the treatment room 3 will be described. In FIG. 1, a particle beam, which is a set of ions (for example, hydrogen ions and carbon ions) generated in the ion source 11 of the injector 10, undergoes pre-acceleration by the pre-stage linear accelerator 12 of the injector 10 to have a predetermined kinetic energy. Is accelerated up to. The particle beam subjected to the pre-acceleration passes through the vacuum duct 13 of the low energy beam transport system and is guided to the synchrotron 21 while being deflected, converged and diverged by the electromagnets 14 to 20, and subjected to the trajectory correction.

The electromagnet 22 (22a, 22b, 22c, 22d) is set so that the particle beam takes a circular orbit in the synchrotron 21, and the synchrotron 21 is repeatedly subjected to the acceleration electric field formed by the high frequency acceleration cavity 23. The particle beam is repeatedly accelerated by the accelerating electric field of the high frequency accelerating cavity 23, and its kinetic energy increases with acceleration. As the kinetic energy increases, the magnetic field strength necessary for deflection of the particle beam changes, so the operating parameters of accelerator devices such as the electromagnets 22 (22a, 22b, 22c, 22d) that make up the synchrotron 21 change with time. To do.

When the particle beam in the synchrotron 21 reaches a predetermined kinetic energy and the particle beam can be taken out, the particle beam is sent out to the high energy beam transport system by the emitting device 24. The particle beam guided to the high energy beam transport system is appropriately guided to the treatment room 3 by the action of the deflection electromagnets 25 to 27.

Although not shown, in the case of a high-energy beam transport system having a rotating gantry, the rotating gantry is set at a predetermined angle and particle beams are transported. Each subsystem that constitutes the accelerator is equipped with a beam monitor, which is used to observe the state of the particle beam.

The particle beam transported to the treatment room 3 is scanned and scattered in a direction perpendicular to the traveling axis of the particle beam by an irradiation device such as a wobbler electromagnet or a scanning electromagnet, a scatterer, a ridge filter, a multileaf collimator, and a bolus (not shown). Through processes such as momentum dispersion, collimation, and compensation, the shape of the affected part of the patient 31 fixed to the patient table 33 and the peak position of the absorbed dose are set so as to match the depth of the affected part, and the dose is administered to the patient 31. ..

The amount of the particle beam administered to the patient 31 is observed by the dose monitor 52 included in the irradiation device 32, and the particle beam irradiation is performed until the administration dose reaches a prescribed dose value. The particle beam irradiation is performed according to a treatment plan, and the treatment plan includes at least one beam condition of the particle beam, an irradiation equipment setting, and an irradiation condition including an irradiation dose value.

When one treatment plan includes a plurality of irradiation conditions and there are two or more kinds of beam conditions included in the irradiation conditions, after administering the irradiation dose set to the irradiation condition corresponding to a certain one beam condition, The accelerator setting is switched to correspond to the next beam condition, and irradiation is started under the next irradiation condition. This operation is repeated until the irradiation dose set for all irradiation conditions included in the treatment plan is administered.
