It should be noted that the scene schematic diagram of the radiation device shown in fig. 1 is only an example, and the radiation device and the scene described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation to the technical solution provided in the embodiment of the present application, and as a person having ordinary skill in the art knows, with the evolution of the radiation device and the occurrence of a new service scene, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.
First, an embodiment of the present application provides a radiation device control system, including: the system comprises a master control system and a slave control system, wherein the master control system sends a target treatment plan to the slave control system based on an ADS data transmission protocol.
The data structure transmitted based on the ADS data transmission protocol is a data structure predefined by the sender and the receiver, and the data structure can be directly read by the sender and the receiver. Therefore, after receiving the data, the receiving party can directly use the data without analyzing the data. Therefore, after the slave control system in the radiation device control system provided by the embodiment of the application receives the target treatment plan sent by the master control system, the treatment plan data can be directly used to control the radiation device to execute radiation delivery without analyzing the treatment plan, so that the transmission efficiency of the treatment plan and the correctness of the transmission of the treatment plan data are improved, and the communication efficiency between the master control system and the slave control system is improved.
It will be appreciated that to ensure that the transmitted target treatment plan data can be read directly from the control system, the master control system needs to process the target treatment plan data before sending the target treatment plan, for example: the target treatment plan data is organized into a predetermined data structure so that it can be read directly from the control system.
In some embodiments, the master control system and the slave control system of the radiation device perform real-time data communication through a socket protocol. In some embodiments, the real-time data includes command data, state machine data, real-time operating data of the radiation device (e.g., real-time position data of the couch, real-time angle data of the rotating gantry), and the like.
In the related art, when transmitting a target treatment plan to a slave control system, a master control system of a radiation device control system takes a field in the target treatment plan as a transmission unit and transmits all fields included in the target treatment plan to the slave control system step by step. Namely: the master control system sends treatment plan data of a portal to the slave control system, and the slave control system controls the radiation equipment to carry out radiation delivery on the portal according to the treatment plan data of the portal; after the slave control system finishes the radiation delivery of the radiation field, the master control system sends the treatment plan data of the next radiation field, and since the slave control system is in a waiting state when the master control system sends the treatment plan data of each radiation field, the radiation delivery process for executing the target treatment plan is very time-consuming.
In some embodiments, the master control system of the radiation apparatus of the present application, when transmitting the target treatment plan to the slave control system, transmits the treatment plan data of all fields contained in the target treatment plan to the slave control system at once. In this way, after the slave control system finishes the radiation delivery of one field, the radiation delivery of the next field can be continued without waiting, and the radiation delivery time of the target treatment plan is greatly saved.
An embodiment of the present application further provides a radiation device control system, where the slave control system includes one or more processors, and the processors are configured to execute a radiation delivery method as shown in fig. 2, where the radiation delivery method specifically includes the following steps S210 to S220:
s210: treatment plan data for all fields contained in the target treatment plan are acquired.
Treatment plan data for all fields contained by the target treatment plan, which refers to the treatment plan that needs to be executed/delivered, is acquired from a processor of the control system. Typically, a treatment plan contains multiple fields, and the treatment plan data for each field includes a plurality of treatment parameters, including but not limited to: beam energy, intensity, direction, size and/or shape, etc.
In an embodiment of the present application, the processor of the slave control system obtains treatment plan data for all fields encompassed by the target treatment plan from the master control system.
S220: and controlling the radiation equipment to sequentially execute radiation delivery aiming at all the fields according to the preset delivery sequence according to the treatment plan data of all the fields and the preset delivery sequence of all the fields.
After the treatment plan data of all the fields contained in the target treatment plan are acquired by the processor of the slave control system, the radiation equipment is controlled to sequentially execute radiation delivery aiming at all the fields according to the treatment plan data of all the fields and the preset delivery sequence of all the fields.
The slave control system of the radiation device control system in the embodiment of the application acquires treatment plan data of all fields included in the target treatment plan at one time. In this way, after the slave control system finishes the radiation delivery of one field, the radiation delivery of the next field can be continued without waiting, and the radiation delivery time of the target treatment plan is greatly saved.
In the present embodiment, the delivery order of all fields is generally determined in the treatment planning system, and is included in the target treatment plan. Therefore, when the slave control system acquires treatment plan data of all fields included in the target treatment plan, the delivery order of all fields is also acquired at the same time.
In some embodiments, after receiving the treatment plan data of all fields of the target treatment plan sent by the master control system, the slave control system controls the radiation device to sequentially perform radiation delivery on all fields according to the preset delivery sequence of all fields. For example: the slave control system controls the treatment couch and the rotating frame of the radiation device to move to the initial irradiation position of the first field according to the treatment plan data of the first field, then sends a radiation delivery starting confirmation message to the user, and controls the radiation source of the radiation device to start to perform radiation delivery on the first field in response to the radiation delivery starting confirmation of the user; after the radiation delivery of the first field is determined to be finished, the slave control system controls the treatment couch and the rotating frame of the radiation device to move to the initial irradiation position of the second field according to the treatment plan data of the second field, then sends the starting radiation delivery confirmation information to the user again, and controls the radiation source of the radiation device to start to carry out radiation delivery on the second field in response to the starting radiation delivery confirmation of the user; and so on until the radiation delivery of all fields encompassed by the target treatment plan is completed.
In this embodiment, after the control system completes the radiation delivery of one field and before the radiation delivery of the next field starts, the slave control system needs to send a start radiation delivery confirmation message to the user to indicate the start of the radiation delivery by the user, so that the radiation delivery process of the target treatment plan is complicated and time-consuming.
Based on this, the present application provides a method for automatically performing radiation delivery after acquiring treatment plan data of all fields included in a target treatment plan from a control system, as shown in fig. 3, the method includes steps S310 to S320:
s310: and sending starting radiation delivery confirmation information aiming at the first field in all fields according to the preset delivery sequence of all fields.
After the treatment plan data of all fields contained in the target treatment plan are acquired, according to a preset delivery sequence of all fields, the starting radiation delivery confirmation information is sent to the user for the first field in all fields, and the user can interact with the slave control system according to the confirmation information prompt (for example, clicking a touch screen of the slave control system by using a finger or clicking a corresponding button on an interactive interface of the slave control system by using a mouse), so as to confirm whether radiation delivery is started.
S320: determining to start radiation delivery, and controlling the radiation device to sequentially execute radiation delivery for all the fields according to the treatment plan data of all the fields.
The slave control system determines to start radiation delivery according to the start radiation delivery confirmation information sent by the user, and controls the radiation equipment to sequentially execute radiation delivery aiming at all the fields according to the treatment plan data of all the fields.
In some embodiments, it is determined to initiate radiation delivery, and the radiation device is controlled to sequentially perform radiation delivery for all fields according to the treatment plan data for all fields, including as in steps S4013-S4019 in fig. 4:
the slave control system, upon determining to initiate radiation delivery, controls the radiation device to perform radiation delivery for the first field in accordance with the treatment plan data for the first field.
And after determining that the radiation device performs the radiation delivery aiming at the first portal is completed, the slave control system directly controls the radiation device to perform the radiation delivery aiming at the second portal according to the treatment plan data of the second portal. And, after determining that the radiation device performs the radiation delivery for the second portal is completed, directly controlling the radiation device to perform the radiation delivery for the third portal according to the treatment plan data for the third portal.
And so on, the control process (S4015-S4018 in figure 4) is repeated until the radiation delivery of all the fields is completed, and the treatment is finished. Wherein the first portal and the second portal, the second portal and the third portal are two portals adjacent to each other in the delivery sequence.
According to the embodiment of the application, the starting radiation delivery confirmation information is sent to the user only before the radiation device is controlled to execute the radiation delivery of the first field in all fields contained in the target treatment plan, and after the user confirms the starting radiation delivery, when the radiation device is controlled to execute the radiation delivery of the subsequent field, the radiation device is automatically controlled from the control system to execute the radiation delivery of the subsequent field without sending the starting radiation delivery confirmation information to the user again, so that the radiation delivery time of the target treatment plan is shortened, and the utilization rate of the radiation device is improved.
In some embodiments, before controlling the radiation device to perform radiation delivery for a next field (e.g., a second field or a third field) from the control system, the radiation delivery control method provided by the embodiments of the present application further includes: and determining the existence of the next radiation field.
As shown in fig. 4, in some embodiments, it may be determined whether there is a next portal through step S4018. When the next portal is present, that is: when the determination result of step S4018 in fig. 4 is yes, step 4015 is executed, in which: continuing to control radiation delivery for the next field; when the next portal is not present, that is: when the determination result of step S4018 in fig. 4 is "no", step S4019 is performed to end the treatment.
In some embodiments, the slave control system determines whether the radiation device performs radiation delivery for the current portal according to the radiation delivery status of the current portal (e.g., the first portal or the second portal).
As shown in fig. 3, in some embodiments, during the radiation delivery of the current portal, the radiation delivery status of the current portal is continuously acquired from the control system to determine whether the radiation delivery of the current portal is completed. In some embodiments, during radiation delivery, a field may include a plurality of radiation delivery states. Illustratively, the radiation delivery state may include: prepare state, Ready state, Radiation state, repetition state, Complete state, etc.
In some embodiments, when the radiation delivery state of the current portal acquired from the control system is a preset state, it is determined that the radiation device performs radiation delivery completion for the current portal.
Wherein the preset state is a state indicating that radiation delivery for the current portal is complete. For example: a repetition state or a Complete state.
Embodiments of the present application further provide a radiation apparatus, which includes a treatment couch, a radiation source, a gantry for carrying the radiation source, and the radiation apparatus control system of any of the above embodiments.
By controlling the movement of the couch, the radiation source, the gantry with the radiation apparatus control system, the radiation delivery for the target treatment plan is performed.
