Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
FIG. 1 is a schematic flow chart of a radiation control repair method in one embodiment, as shown in FIG. 1, comprising:
step S110: control initialization is performed by loading peripheral source files and core source files.
The RT system kills cancer cells by radiating high-energy particles (neutrons, alpha particles and the like) on the focus of a patient between treatments to achieve the treatment effect. The RT system starts the radiation control by the moment the patient focus starts between high energy particle radiation treatments. In an RT system, a control class board card for controlling a radiation treatment process is typically installed near a radiation area within a treatment room to control the radiation treatment process, and the control class board card receives radiation to varying degrees during the radiation treatment process. Especially, after a field programmable gate array (FPGA, field Programmable Gate Array) processor based on a Static Random Access Memory (SRAM) process on a board is subjected to a certain dose of radiation, an internal Memory unit, such as an instruction ram CRAM (Configure RAM), may have a single bit or multiple bits flipped, so that the function of a control board card may be interrupted or abnormal with a high probability, which brings great hidden trouble to the reliable operation of the board in a radiation area between treatments and the safety of patients.
In this embodiment, the source file of the conventional technology is divided into at least two parts, namely, a peripheral source file and a Core source file (Core image), for example, a more important part of the source file may be set as the Core source file, and the rest may be set as the peripheral source file. When radiation control is started, the control type board card is controlled and initialized by loading the peripheral source file and the core source file, for example, the control and initialization can be performed on an FPGA processor on a single board. The content of the control initialization may include radiation dose, radiation time, etc.
Step S120: it is determined whether bit flipping of the internal memory cells occurs. If yes, go to step S130.
Step S130: the core source file is reloaded from a remote host located in the non-radiating area.
Specifically, it is determined whether a bit flip has occurred in the internal storage unit, and upon detecting that a bit flip has occurred in the internal storage unit, the core source file is reloaded from a remote host located in the non-radial region. Since the remote host is located in the non-radiating area, the core source files deposited in the remote host are not affected by the radiation.
Step S140: and repairing the internal storage unit according to the reloaded core source file.
Specifically, the internal storage unit generates bit overturn to cause the error of the core source file, and the internal storage unit is repaired according to the reloaded core source file, namely the core source file stored in the internal storage unit is corrected, so that the purpose of resisting the particle overturn is achieved, and the influence on the radiotherapy process caused by the bit overturn of the internal storage unit is avoided. In other embodiments, the peripheral source file may also be reloaded when a bit flip of the internal memory location is detected.
According to the radiation control repair method, when the bit overturn of the internal storage unit is detected, the core source file is reloaded from the remote host positioned in the non-radiation area, the internal storage unit is repaired according to the reloaded core source file, and the core source file which is in error due to the influence of radiation in the internal storage unit is corrected so as to achieve the purpose of resisting the particle overturn, thereby avoiding the function interruption or failure of the control board card caused by the bit overturn of the internal storage unit, improving the working stability of the control board card and ensuring the safety of patients receiving radiation treatment; meanwhile, since the reloaded core source file is stored in a remote host located in the non-radiation area, the error of the core source file is avoided.
FIG. 2 is a flow chart of a radiation control repair method according to another embodiment. As shown in fig. 2, the radiation control repair method includes the steps of:
step S110: at the start of radiation control, control initialization is performed by loading the peripheral source file and the core source file. Step S110 specifically includes steps S111 to S113.
Step S111: the peripheral source files are loaded from a peripheral storage device located in a weakly or non-radiating area.
Specifically, the peripheral storage device may refer to a local Flash in the conventional technology that stores source files. The peripheral storage device is located in a weakly radiating area or a non-radiating area within the treatment room such that peripheral source files stored in the peripheral storage device are less affected by radiation.
Illustratively, the peripheral source file is divided into two portions and stored in two local Flash respectively. The FPGA processor loads a part of peripheral source files through one local Flash by adopting an Active Serial (AS) mode, and loads the rest of peripheral source files through the other local Flash by adopting a fast passive parallel (FPP, fast Passive Parallel) mode, wherein the loaded working clock can reach 100MHz at the highest speed, and the loading speed is higher.
Further, step S111 may include loading the peripheral source file from a peripheral storage device located in the low emissivity region via a differential serial peripheral interface or a fiber serial peripheral interface.
Specifically, a communication distance between the FPGA processor and the local Flash is prolonged by using a differential serial peripheral interface (SPI, serial Peripheral Interface) or a light serial peripheral interface, so that the local Flash for storing the peripheral source file can be placed in a weak radiation area or a non-radiation area far away from a near radiation area, and the problem that the peripheral source file cannot be loaded due to failure of the local Flash caused by radiation is avoided.
Step S112: the host connection interface is initialized, and the core source file is loaded from the remote host through the host connection interface.
Specifically, the core source file is stored in the remote host, and the remote host may be located in an operating room without radiation, so that the core source file stored in the remote host is not affected by the radiation.
After loading the peripheral source files, the FPGA processor initializes the HOST connection interface and loads the core source files from a remote HOST (HOST) via the HOST connection interface. For example, the host connection interface is a high-speed serial computer expansion bus (PCIE, peripheral component interconnect express) fiber interface, that is, a CvP loading manner is adopted when loading the core source file. The optical transmission rate through the PCIE optical fiber interface can be as high as 8G, so that the core source file is rapidly transmitted and loaded, and the real-time requirements can be well met in some control links with higher real-time requirements. In addition, when the core source file is reloaded in step S130, the core source file is reloaded by the remote host through the PCIE optical fiber interface, so that the repair rate of bit flipping of the internal storage unit can be improved.
Step S113: initializing a control device according to the peripheral source file and the core source file.
Specifically, after the core source file and the peripheral source file are loaded, initializing a control device according to the peripheral source file and the core source file, for example, initializing initial radiotherapy parameters of the FPGA processor, thereby entering a user mode, and repairing bit flipping of the internal storage unit.
Step S120: it is determined whether bit flipping of the internal memory cells occurs. If yes, go to step S130; otherwise, step S120 is continued to determine whether the internal memory unit is bit flipped.
Step S130: the core source file is reloaded from a remote host located in the non-radiating area.
Step S140: and repairing the internal storage unit according to the reloaded core source file. Step S140 specifically includes step S141: and refreshing the memory area with bit flipping in the internal memory unit.
Specifically, when the bit overturn of the internal storage unit is detected, reloading the core source file from a remote host positioned in the non-radiation area, and refreshing the storage area with the bit overturn in the internal storage unit according to the reloaded correct core source file, thereby correcting the storage content in the bit overturn area in the internal storage unit to be consistent with the correct core source file, ensuring the correctness of the core source file in the internal storage unit, avoiding interruption or abnormality of the control board card function caused by radiation, ensuring the safety of a patient receiving radiotherapy, and ensuring the safety of a single board in the radiation area between treatments; in addition, since the core source file is stored in the remote host located in the non-radiation area and the peripheral source file is stored in the peripheral storage device located in the weak radiation area or the non-radiation area, the probability of error occurrence between the core source file and the peripheral source file can be reduced.
Fig. 3 is a schematic structural diagram of an embodiment of a radiation control repair device, as shown in fig. 3, and in one embodiment, the radiation control repair device 300 includes a controller 310 located in a near radiation area, a peripheral storage device 320 located in a weak radiation area or no radiation area, and a remote host 330 located in a no radiation area, where the controller 310 and the remote host 330 perform data transmission through a host connection interface (not shown). For example, the controller 310 is located in a near-radiation region within the treatment room 340, the peripheral storage device 320 is located in a weak radiation region or a no radiation region within the treatment room 340, and the controller 310 is located in the operation room 350, and the regions within the operation room 350 all belong to the no radiation region.
At the start of radiation control, the controller 310 performs control initialization by loading peripheral source files from the peripheral storage device 320 and core source files from the remote host 330; reloading the core source file from the remote host 330 when the controller 310 detects that a bit flip has occurred in an internal storage unit (not shown); the controller 310 repairs the internal storage unit according to the reloaded core source file. Wherein the internal memory unit may belong to a memory unit within the controller.
