Japanese Patent Application Laid-Open No. 2018-038628

BACKGROUND ART As radiation therapy for cancer, particle beam therapy is known in which an ion beam such as protons or heavy ions is irradiated to a cancer-affected part of a patient for treatment.

A particle beam therapy system requires high-precision beam position adjustment in order to introduce an ion beam into an affected area, and it takes a lot of time for the adjustment and testing. As one of the techniques for minimizing the time, there is the technique described in the above-mentioned Patent Document 1.

In a particle beam therapy system, if the entire system including the operation screen is replaced when the system is updated, it will take a very long time for adjustment and testing. Therefore, there is a problem in that the period during which the treatment is stopped is prolonged, and the patient, which could be treated when the existing system was in operation, cannot be treated.

Due to these problems, there is concern that the income source for equipment maintenance will decrease and the supply of equipment will be insufficient to meet the demand of patients to be treated.

When performing update work to add new equipment to an existing treatment system, it is not possible to subdivide the operation system, control system, equipment, etc., including the operation screen of the system, and gradually replace each part. It is possible. However, considering the case of a major equipment update, it is essential to adjust and test the combination of the existing and new parts, so it is not possible to handle the existing system outside the treatment hours (for example, at night or on holidays). There is clearly a lack of time. Therefore, there is still a need for a time-saving and labor-saving approach.

Furthermore, if there is a problem with the new system after the update, even if it is restored to the existing system, it cannot be used immediately, and adjustments and tests are required, so there is a high risk of updating work. There is

Thus, there is a demand for a method of updating the operation screen and the like as simply as possible when updating the system.

The present invention has been made in view of the above-mentioned problems, and it is possible to add, adjust, and test a new system during times when treatment is not being performed, such as nights and holidays, while maintaining treatment with the existing system. It is an object of the present invention to provide a particle beam therapy system and an operation screen updating method for the particle beam therapy system that can perform update work such as.

The present invention includes a plurality of means for solving the above problems. a radiation source, an irradiation device that irradiates the affected area with the particle beam generated by the particle beam source, a transport system that transports the particle beam from the particle beam source to the irradiation device, the particle beam source, A control device that controls the operation of the transport system and the irradiation device, and an operation terminal that has an operation screen that displays the state of the particle beam therapy system, wherein the control device is controlled by ON/OFF of a mask signal. a non-release mode in which an image or information related to a specific device is masked and displayed on the operation screen of the operation terminal; and an image or information related to the specific device is displayed on the operation screen without being masked. The operation screen of the operation terminal displays an image or information related to the specific device in a masked state in the non-release mode, and displays the image or information related to the specific device in a masked state in the release mode. displays an image or information related to the specific device.

According to the present invention, it is possible to carry out the update work while maintaining the treatment by the existing system, during the time when the treatment is not performed, such as at night or on holidays. Problems, configurations, and effects other than those described above will be clarified by the following description of the embodiments.

An embodiment of a particle beam therapy system and an operation screen update method for the particle beam therapy system of the present invention will be described with reference to FIGS. 1 to 11. FIG.

First, the general configuration of the particle beam irradiation system of the present invention will be described with reference to FIG. FIG. 1 shows the overall configuration of the particle beam irradiation system of this embodiment.

A particle beam therapy system 100 of this embodiment as shown in FIG. , a beam irradiation device 3 , a control system 4 , and an operation terminal 40 .

A charged particle beam generator 1 is a device that generates a charged particle beam 12 to irradiate a diseased part 13 a of a patient 13 , and has an ion source 15 a , a pre-stage accelerator 15 b and a circular accelerator 16 . The ion source 15a is connected to the upstream side of the pre-stage accelerator 15b, and the circular accelerator 16 is connected to the downstream side of the pre-stage accelerator 15b.

In FIG. 1, a synchrotron is described as an example of the circular accelerator 16, but in addition to the synchrotron accelerator, various known accelerators such as a cyclotron accelerator and a synchrocyclotron accelerator can be used. In that case, the pre-accelerator 15b may not be required.

The type of the charged particle beam 12 generated by the ion source 15a is also not particularly limited, and examples of the charged particle beam 12 that irradiates the affected area 13a of the patient 13 include protons and heavy particles such as carbon and helium.

The beam transport system 2 is connected downstream of the charged particle beam generator 1 and connects the charged particle beam generator 1 and the beam irradiation device 3 . The beam transport system 2 transports the charged particle beam 12 from the charged particle beam generator 1 to the beam irradiation device 3 .

The beam irradiation device 3 is a device for irradiating the affected area 13a of the patient with the charged particle beam 12 generated by the charged particle beam generator 1 and transported by the beam transport system 2. As shown in FIG. It generally comprises a treatment table 10 on which a patient 13 is placed, an irradiation nozzle 11 and a rotating gantry 14 .

A plurality of beam irradiation devices 3 can be provided. In this case, the charged particle beam 12 is guided to the beam irradiation device 3 for beam irradiation by controlling the corresponding bending electromagnet 9 among the plurality of bending electromagnets 9 provided. be.

The irradiation nozzle 11 has an upstream beam monitor, a scanning electromagnet, a dose monitor, and a downstream beam monitor (each omitted for convenience of illustration) arranged along the beam path to form a beam irradiation field.

The upstream beam monitor measures the passage position and beam width (beam diameter) of the charged particle beam 12 that has entered the irradiation nozzle 11 .

The scanning electromagnets include a first scanning electromagnet that deflects and scans the passing charged particle beam 12 in a first direction (eg, X-axis direction) and a second scanning electromagnet that is perpendicular to the first direction (eg, Y-axis direction). ) for deflecting and scanning the charged particle beam 12 . Here, the X-axis direction is one direction within a plane perpendicular to the traveling direction of the charged particle beam 12 incident on the irradiation nozzle 11, and the Y-axis direction is within the plane and perpendicular to the X-axis. direction.

The dose monitor measures the irradiation dose of the passing charged particle beam 12 . That is, the dose monitor is a monitor that monitors the irradiation dose of the charged particle beam 12 irradiated to the patient.

The downstream beam monitor is installed downstream of the scanning electromagnet and measures the position and beam width of the charged particle beam 12 passing therethrough. That is, the downstream beam monitor is a monitor that measures the position and beam width of the charged particle beam 12 scanned by the scanning electromagnet.

The method of irradiating the charged particle beam 12 in the present invention is not particularly limited. , a continuous spot irradiation method in which the charged particle beam 12 is not stopped between spots, a wobbler method, a double scatterer method, etc. After spreading the distribution of the charged particle beam 12, the dose is adjusted to the shape of the affected area 13a using a collimator or a bolus. Irradiation methods that form a distribution can be employed.

The rotating gantry 14 is configured to be rotatable around an isocenter (not shown) and determines the irradiation angle of the beam. By rotating the rotating gantry 14, the irradiation angle of the charged particle beam 12 that irradiates the patient 13 can be changed.

The beam irradiation device 3 can also be a fixed irradiation device that does not have the rotating gantry 14 .

A treatment table 10 is arranged in a treatment room and is a bed on which a patient 13 is placed. Based on instructions from the control system 4, the treatment table 10 can move in directions of three orthogonal axes, and can also move in so-called six-axis directions, rotating about each axis. By these movements and rotations, the position of the affected part 13a of the patient 13 can be moved to a desired position.

The treatment planning device 6 uses a CT image created by a CT image creation device (not shown) to determine the positions of the irradiation spots for irradiating the affected area with a uniform dose and the target dose for each irradiation spot. calculate.

The control system 4 is connected to the charged particle beam generation device 1, the beam transport system 2, the beam irradiation device 3, the treatment planning device 6, the operation terminal 40, etc., and controls the charged particle beam generation device 1, the beam transport system 2, and the It controls the operation of each device that constitutes the beam irradiation device 3 .

The control system 4 roughly includes a central controller 5, an accelerator/transport system control system 7, and an irradiation control system 8, as shown in FIG.

Central controller 5 is connected to treatment planning device 6 , accelerator/transport system control system 7 , irradiation control system 8 and operation terminal 40 . Based on the setting data from the treatment planning device 6, the central control unit 5 controls setting values of operation parameters for accelerator operation, operation parameters for forming an irradiation field, planned beam position and beam width, dose It has a function to calculate the setting value of These operating parameters and monitor setting values are output from the central controller 5 to the accelerator/transport system control system 7 , the irradiation control system 8 and the operation terminal 40 .

In the central control device 5 of the present embodiment, the display screen 40a of the operation terminal 40 is masked with an image or information related to a specific device by ON/OFF of the mask signal, which is a parameter of the central control device 5. and a release mode in which images or information related to a particular device are displayed on the display screen 40a without being masked.

Note that, in this embodiment, the function cannot be used when it is masked. For example, the functions in this embodiment include operation by pressing a button, display of control parameters, status display lamps for equipment and conditions, command operation and display function such as input by keyboard, input operation, and the like.

With such control, in the non-release mode in which the mask signal is ON, the image or information related to the specific device is not displayed on the display screen 40a of the operation terminal 40 due to the masking process, and the device is disabled. In contrast, in release mode, where the mask signal is OFF, the function is released and an image or information associated with a particular device is displayed. Details thereof will be described later.

The images and information displayed/hidden by such a mask include the third beam transport system 2c, the third treatment room beam irradiation device 3c, and the third beam transport system additionally installed in the particle beam therapy system 100. The image or information related to the bending electromagnet 9c (see FIG. 4 etc. for details), and the control parameters of each of the additionally installed devices recorded in the central controller 5 of the control system 4 included.

In addition, when the mask signal is turned off, the central control unit 5 releases multiple, preferably all, images or information related to the specific device hidden by the mask at once. is desirable.

For example, when the mask signal is turned off and the function is released, it is desirable that the control parameters of the additionally installed specific device recorded in the central controller 5 of the control system 4 are also released.

Considering the safety of the mask signal, it is desirable that the input instruction for switching ON/OFF of the mask signal is input from a device other than the operation terminal 40 . For example, it is desirable to enable ON/OFF switching only by command operation in the central control unit 5 that can be used only by a specific user determined by the system designer. The command operation of the central control unit 5 can also be executed by remote control using an external terminal.

The mask signal described above is a parameter held by the central control unit 5 and is periodically transmitted to the operation terminal 40 . However, it may be transmitted to a device other than the operation terminal 40 .

Further, as shown in FIG. 2, after the central control unit 5 transmits the mask signal to the operation terminal 40, the operation terminal 40 transmits the mask signal back to the central control unit 5, thereby improving reliability. It is desirable to ensure FIG. 2 is a diagram showing exchange of mask signals between the central control unit and the operation terminal.

With such a configuration, it is desirable that the central control unit 5 switches between the release mode and the non-release mode after receiving feedback from the operation terminal 40 when changing ON/OFF of the mask signal.

The accelerator/transportation system control system 7 is connected to the charged particle beam generator 1 and the beam transport system 2 and controls the operations of the devices that make up the charged particle beam generator 1 and the beam transport system 2 .

The irradiation control system 8 is connected to the beam irradiation device 3 and controls the operation of each device constituting the beam irradiation device 3 .

The operation terminal 40 is a computer that displays the state of the particle beam therapy system 100, and has an input device and a display screen 40a for an operator (medical worker such as a doctor or operator) to input data and instruction signals.

The display screen 40 a displays the operating status, treatment information, and control parameters of the devices that make up the particle beam therapy system, corresponding to the data transmitted from the central controller 5 . However, other functions may be displayed.

These control system 4, accelerator/transport system control system 7, irradiation control system 8, treatment planning device 6, and operation terminal 40 have a central processing unit (CPU) and a memory connected to the CPU.

The control system 4 reads various operation control programs related to irradiation of each device constituting the particle beam therapy system 100 from the treatment plan created by the treatment planning device 6, executes the read program, and controls the accelerator/transport By outputting commands via the system control system 7 and the irradiation control system 8, the operation of each device in the particle beam therapy system 100 is controlled.

It should be noted that the control processing of the operations to be executed may be put together in one program, each of which may be divided into a plurality of programs, or may be a combination thereof.

Also, part or all of the program may be realized by dedicated hardware, or may be modularized. Furthermore, various programs may be installed in each device by a program distribution server or an external storage medium.

Each device may be an independent device connected to a wired or wireless network, or two or more devices may be integrated.

Next, procedures for updating the treatment system in the particle beam therapy system of this embodiment and screens displayed on the operation terminal 40 before and after the update will be described with reference to FIG. 3 and subsequent figures.

First, the configuration of the particle beam therapy system before and after updating will be described with reference to FIGS. 3 and 4. FIG. FIG. 3 is a schematic diagram showing the configuration before adding a treatment room, and FIG. 4 is a schematic diagram showing the configuration after adding a treatment room.

Below, as shown in FIG. 3, the particle beam therapy system includes one circular accelerator 16, beam transport system 2, first treatment room beam irradiation device 3a, second treatment room beam irradiation device 3b, and further, as shown in FIG. has a first beam transport system 2a and bending electromagnet 9a for transporting the beam to the first treatment room beam irradiation device 3a, and a second beam transport system 2b and bending electromagnet 9b for transporting the beam to the second treatment room beam irradiation device 3b. system.

In the future, as shown in FIG. 4, there are plans to add a third beam irradiation system 3c in FIG. It has become.

Renewal of equipment and control system related to the treatment room in such a particle beam therapy system 100 will be described below with reference to FIGS. FIG. 5 is a flowchart for explaining an example of a procedure for adding treatment rooms.

In the procedure shown below, the specific devices to be switched between being displayed and not being displayed by the mask are the third beam transport system 2c, the third treatment room beam irradiation device 3c, and the third beam transport system 2c. It is referred to as a bending electromagnet 9c.

Needless to say, the number and arrangement of treatment rooms vary depending on the equipment, so the explanation is given as a representative example.

First, as shown in FIG. 5, a screen to be displayed on the operation terminal 40 to be used at the time of new construction is created (step S101). A screen is created using a terminal for debugging or an operation terminal 40 delivered to a customer before construction. However, when using a debugging terminal, it is desirable to enter screen data into the operation terminal 40 before construction.

In addition, in the screen creation in this step S101, the first treatment room beam irradiation device 3a scheduled to be constructed at the time of new construction, the first beam transport system 2a related thereto, the second treatment room beam irradiation device 3b, and the second treatment room beam irradiation device 3b related thereto The functions of the third treatment room beam irradiation device 3c other than the beam transport system 2b and the third beam transport system 2c related thereto are also included. Here, the third treatment room beam irradiation device 3c and the like will be described as an example.

After the screen is created, the display and non-display ranges are set by mask processing (step S102).

After that, the charged particle beam generator 1, the beam transport system 2, the first treatment room beam irradiation device 3a, the second treatment room beam irradiation device 3b, the control system 4, and the operation terminal 40 are newly constructed in a hospital or the like (step S103).

After the construction is completed, the system designer or the like operates the central control unit 5 with a command to turn on the mask signal (step S104). As a result, the central controller 5 masks functions related to the third treatment room beam irradiation device 3c and the like (step S104).

By such mask processing, the screen displayed on the operation terminal 40 changes to a screen as shown in FIG. 7 or a screen as shown in FIG. 9, which will be described later in detail.

After that, functional tests are performed on the first treatment room beam irradiation device 3a and the second treatment room beam irradiation device 3b (step S105). In this step S105, not only the functions of the first treatment room beam irradiation device 3a and the second treatment room beam irradiation device 3b are tested, but also the confirmation that the functions of the third treatment room beam irradiation device 3c and the like cannot be used is performed. is desirable.

After functional testing is completed, treatment is initiated (step S106).

When the user of the system decides to add more at any time after the start of treatment, the third treatment room consisting of the third treatment room beam irradiation device 3c, the third beam transport system 2c, the bending electromagnet 9c, etc., are started to be added ( step S107). The period from the start of treatment to the extension is not specified in particular, and is often determined according to the operational status of the particle beam therapy system 100 and the like.

After the installation of the structures such as the beam irradiation device 3c in the third treatment room is completed, the central control device 5 first determines whether or not the update work of the beam irradiation device 3c in the third treatment room has been completed (step S108). When it is determined that the treatment has been completed, the process proceeds to step S112, and treatment using three treatment rooms including the third treatment room beam irradiation apparatus 3c is started (step S112).

On the other hand, when it is determined that the update work of the beam irradiation device 3c in the third treatment room, etc. is not completed, the process proceeds to step S109.

Next, the central controller 5 determines whether or not the present is the treatment period (step S109). When it is determined that it is the treatment period, the process returns to step S108 because the third treatment room beam irradiation device 3c and the like cannot be adjusted. On the other hand, if it is not determined that it is the treatment period, the process proceeds to step S110 in order to adjust the third treatment room beam irradiation device 3c and the like.

Thereafter, the mask signal is turned off by command operation of the central control unit 5 by the system designer or the like (step S110). As a result, the central controller 5 unmasks the functions related to the third treatment room beam irradiation device 3c, etc., and enables the functions of the third treatment room beam irradiation device 3c, etc. (step S110).

After that, a confirmation test of the function of the additional portion related to the third treatment room is performed (step S111). After the function confirmation test, the process returns to step S108 and proceeds to the treatment start step as appropriate.

In this way, it is possible to minimize the update work time by one signal switching operation without replacing the screen.

Next, a specific example of a masking method for the display screen 40a displayed on the operation terminal 40 will be described with reference to FIGS. 6 to 9. FIG. 6 and 8 are diagrams showing examples of operation screens after function release, and FIGS. 7 and 9 are diagrams showing examples of operation screens before function release.

6 and 7 show a method using the mask symbol 41 and an example of use on a screen for displaying the state of the equipment of the entire particle beam therapy system.

As shown in FIG. 6, the mask symbol 41 is not displayed when the mask signal is OFF, and the portion of the mask symbol 41 can be browsed and operated. On the other hand, as shown in FIG. 7, it is displayed when the mask signal is ON, the display of the mask symbol 41 portion becomes invisible, a blank is displayed, and operation of the function is disabled.

6 and 7, dotted lines represent mask symbols 41, which are not displayed on the actual screen. This method can also be used for equipment status display screens, treatment progress confirmation screens for each treatment room, call screens for each treatment room, and the like.

8 and 9 are examples of use on the alarm list display screen.

As shown in FIG. 8, before outputting to the list, if the mask signal is OFF, the information of the third treatment room is also output to the list in addition to the first treatment room and the second treatment room. On the other hand, if the mask signal is ON, as shown in FIG. 9, the information of the third treatment room is masked by inserting processing not to output it to the list. This method is also used in control parameter list screens, registered device list screens, and the like.

Up to this point, the case where only one treatment room is added has been taken as an example, but the update procedure when there are a plurality of treatment rooms and the times are different will be described below with reference to FIGS. 10 and 11. FIG. 10 and 11 are flowcharts for explaining another example of the procedure for adding a treatment room for the particle beam therapy system.

Here, an example will be described in which the first treatment room and the second treatment room are constructed at the time of new construction, and then the expansion of the third treatment room and the expansion of the fourth treatment room are planned later.

First, similarly to step S101 shown in FIG. 5, the display screen 40a of the operation terminal 40 including the finally constructed third and fourth treatment rooms is created (step S201).

Next, the central controller 5 performs mask processing for functions related to the fourth treatment room (step S202). Here, the mask signal corresponding to the mask processing in step S202 is assumed to be a fourth mask signal.

After that, in the same manner as in step S202 described above, the central controller 5 performs masking processing for functions related to the third treatment room (step S203). The mask signal corresponding to the mask processing in step S203 is used as a third mask signal, and a signal different from the fourth mask signal used in step S202 is used. Accordingly, it is desirable to distinguish between a plurality of mask signals and reliably suppress unintended ON/OFF switching of the function of the additional device.

Here, the mask processing is described in the order of the fourth treatment room and the third treatment room, but the order may be reversed and is not particularly limited.

After that, the charged particle beam generator 1, the beam transport system 2, the first treatment room beam irradiation device 3a, the second treatment room beam irradiation device 3b, the control system 4, and the operation terminal 40 are newly constructed in a hospital or the like (step S204).

After the new construction, both the third mask signal and the fourth mask signal are turned ON by command operation of the central controller 5 by the system designer or the like (step S205). As a result, the central controller 5 masks the functions related to the beam irradiation device 3c in the third treatment room, the fourth treatment room, etc. (step S205).

After that, the functional test of the first treatment room beam irradiation device 3a, the second treatment room beam irradiation device 3b, etc. is executed (step S206). In this step S206, as in step S105 shown in FIG. 5, not only the functions of the first treatment room beam irradiation device 3a and the second treatment room beam irradiation device 3b, but also the third treatment room beam irradiation device 3c It is also confirmed that the functions of the 4th treatment room cannot be used.

The following steps S207 to S213 are the same as steps S106 to S112 in FIG. 5 described above, and the details thereof will be omitted. After starting the treatment using the 1-3 treatment rooms in step S213, the process proceeds to step S214 in FIG.

If the user of the system decides to add more treatment rooms at an arbitrary timing after the start of treatment using the first to third treatment rooms, the addition of a fourth treatment room and the like is started (step S214).

After the installation of the structures such as the fourth treatment room is completed, the central controller 5 first determines whether or not the update work for the fourth treatment room has been completed (step S215). When it is determined that the treatment has been completed, the process proceeds to step S219, and treatment using four treatment rooms is started (step S219).

On the other hand, when it is determined that the update work for the fourth treatment room has not been completed, the process proceeds to step S216.

Next, the central controller 5 determines whether or not the present is the treatment period (step S216). When it is determined that it is the treatment period, the process returns to step S215 because adjustment of the fourth treatment room cannot be performed. On the other hand, if it is not determined that it is the treatment period, the process proceeds to step S217 to adjust the fourth treatment room.

After that, the fourth mask signal is turned OFF by the system designer or the like command-operating the central controller 5 (step S217). As a result, the central controller 5 unmasks the functions related to the fourth treatment room and makes the functions of the fourth treatment room available (step S217).

After that, a confirmation test of the function of the additional portion related to the fourth treatment room is performed (step S218). After the function confirmation test, the process returns to step S215 and proceeds to the treatment start step as appropriate.

In this way, when the installation period is divided into a plurality of times, it is desirable to realize the mask function by using a plurality of mask signals.

Next, the effects of this embodiment will be described.

In the particle beam therapy system 100 of the present embodiment described above, the central controller 5 of the control system 4 controls the third beam transport system 2c, the third treatment room beam irradiation device 3c, the third beam a non-release mode in which an image or information related to the bending electromagnet 9c for the transport system 2c is masked and displayed on the display screen 40a of the operation terminal 40; a third beam transport system 2c; The display screen 40a of the operation terminal 40 is switched between a release mode in which an image or information related to the bending electromagnet 9c for the third beam transport system 2c is displayed without being masked, and the non-release mode is displayed on the display screen 40a of the operation terminal 40. , an image or information related to the third beam transport system 2c, the beam irradiation device 3c in the third treatment room, and the bending electromagnet 9c for the third beam transport system 2c is displayed in a masked state. Images or information relating to the third beam transport system 2c, the third treatment room beam irradiation device 3c and the bending electromagnet 9c for the third beam transport system 2c are displayed.

With such a configuration, while maintaining treatment with the existing system, the operation screen can be updated during times when treatment is not being performed, such as at night or on holidays. In doing so, it is possible to reduce the impact of stopping treatment in the existing system, and to implement update work such as adding treatment rooms with minimal impact on the existing system.

In addition, since it is not necessary to replace a single treatment system and update it, it is possible to suppress the extremely long time required for adjustment and testing, and to prolong the period of treatment suspension and the accompanying It is possible to prevent the problem of not being able to treat the number of patients that could be treated when the existing system was in operation.

In addition, when the mask signal is turned off, the central controller 5 of the control system 4 controls the plurality of third beam transport systems 2c, the third treatment room beam irradiation device 3c, the third Since the image or information related to the bending electromagnet 9c for the beam transport system 2c is released at once, it is not necessary to release the image or information in multiple times, and switching can be easily performed. In addition, it is possible to prevent some of the additional devices from being in a released state different from that of the other devices.

Further, the central controller 5 of the control system 4 transmits a change signal to the operation terminal 40 and receives feedback from the operation terminal 40 when changing ON/OFF of the mask signal. Then, by switching the release mode or the non-release mode, switching is performed after confirming that all devices in the particle beam therapy system 100 have the same parameters. Reliability can be ensured.

Also, the central controller 5 of the control system 4 is associated with the restricted third beam transport system 2c, the third treatment room beam irradiation device 3c and the bending electromagnet 9c for the third beam transport system 2c in the release mode. By releasing the functions and shifting to testing of a system that combines the released functions with the functions of the existing equipment, it is possible to quickly bring the additional equipment to a state where treatment can be performed, and the impact of stopping treatment in the existing system. can be reduced more effectively.

Furthermore, in the non-release mode, a blank is displayed as a mask symbol 41 in a portion where an image or information is displayed on the display screen 40a. Since it is possible to use a blanked part, there is no need to separately create different operation screens before and after the expansion, and the update switching of the system can be performed more smoothly.

Also, the input instruction for switching ON/OFF of the mask signal is input from a device other than the operation terminal 40, thereby preventing unnecessary switching of the mask signal when the user erroneously operates the particle beam therapy system 100 during treatment. Since this can be prevented, the particle beam therapy system 100 can be operated more stably.

Furthermore, in release mode, the additionally installed third beam transport system 2c, the third treatment room beam irradiation device 3c, the deflection for the third beam transport system 2c, recorded in the central controller 5 of the control system 4 By releasing the control parameters of the electromagnet 9c as well, it is possible to prevent new control parameters from being introduced into the central control unit 5 at the time of expansion and to suppress unnecessary use before the expansion. This enables stable system operation.

When there are a plurality of target beam transport systems 2 and beam irradiation devices 3 to be displayed or hidden by the mask, the mask signal can be changed to the target device by using individual mask signals. This can be reliably suppressed, and update work can be executed more stably.
