For example, an interface is provided between the system and the relevant user or institution, before acquiring the relevant information, the system needs to send an acquisition request to the user or institution through the interface, and acquire the relevant information after receiving the consent information fed back by the user or institution.
The application is further illustrated below in conjunction with the examples.
Example 1
An embodiment of the present application provides an apparatus for detecting an execution status of an optional radiotherapy plan, where fig. 1 is a schematic diagram of the apparatus for detecting an execution status of an optional radiotherapy plan, as shown in fig. 1, including: acquisition section 101, analysis section 102, analog calculation section 103, and determination section 104.
Specifically, the obtaining unit 101 is configured to obtain a log file generated by the target accelerator when executing a first radiotherapy plan, where the first radiotherapy plan is an execution radiotherapy plan formulated for the target object, and the first radiotherapy plan includes at least first dose distribution information formulated for the target object.
Optionally, the target object is a patient needing radiotherapy, and the target accelerator includes, but is not limited to, proton accelerators, linear accelerators and other accelerators, and the type and model of the target accelerator are not particularly limited.
In addition, in the present application, a detection means (hereinafter simply referred to as detection means) of the execution status of the radiotherapy plan may set a folder for storing log files on the target accelerator as a monitored folder. After the target accelerator executes the first radiotherapy plan, a new log file is generated under the monitored folder corresponding to the target accelerator, and then the detection device can detect the newly generated log file in the monitored folder and read the log file.
It should be noted that in the prior art, the logs of the target accelerator are usually obtained by adopting a manual searching mode, and the generated logs of the target accelerator are often existed under a plurality of different folders for different manufacturers and models, so that the searching personnel are required to continuously find the latest log files from the plurality of folders by adopting the manual searching mode, the searching efficiency is low, and the risk of missing the log files due to human negligence exists.
In the application, the detection device adopts an automatic mode, and the log file of the target accelerator is loaded into the detection device under the condition that a user does not feel, so that the problems of complicated log file acquisition steps and poor timeliness caused by a manual retrieval mode can be solved, and the risk of missing the log file caused by human negligence can be avoided.
Further, the first dose distribution information included in the first radiotherapy plan is dose distribution information personalized according to the target object, wherein the actual situation of the target object is taken into account when determining the first dose distribution information. For example, the first dose distribution information is formulated based on comprehensive evaluation of the condition of the radiotherapy target zone of the target object and the surrounding organs at risk, or it is also necessary to consider the influence of the radioactivity of the accelerator and the posture of the target object at the same time, so as to ensure that unnecessary irradiation of the organs at risk of the target object is avoided as much as possible while the radiation dose can be maximally concentrated to the radiotherapy target zone of the target object.
Further, the first dose distribution information may be obtained in various manners, for example, by acquiring a medical image of the target object, a contour sketching image of the radiotherapy target area, and a contour sketching image of the organ at risk, processing the medical image, the contour sketching image of the radiotherapy target area, and the contour sketching image of the organ at risk by using a neural network model, and predicting to obtain the first dose distribution information corresponding to the target object. Or, using a simulation algorithm to calculate, based on the medical image of the target object, the contour sketch image of the radiotherapy target area and the contour sketch image of the organs at risk, obtaining the first dose distribution information corresponding to the target object.
Further, the detection device further includes an analysis unit 102, where the analysis unit 102 is configured to analyze the log file, and generate a second radiotherapy plan according to an analysis result.
Optionally, the plan parameters in the second radiotherapy plan are determined by file information in the log file.
Specifically, various log information such as the start time of the target accelerator, the shutdown time of the target accelerator, patient information actually used by the target accelerator in executing the radiotherapy plan, field information, beam information, and the like are included in the log file.
Optionally, the detection device may call a log analysis algorithm corresponding to the target accelerator according to the equipment model information and manufacturer information of the target accelerator, and then analyze the log file according to the log analysis algorithm to obtain an analysis result, where the analysis result includes various log information in the log file. And finally, the detection device generates a second radiotherapy plan according to the analysis result. Wherein the file format of the second radiotherapy plan is a Dicom file format.
It should be noted that the second radiotherapy plan may reflect the actual execution status of the target accelerator, and the plan parameters in the second radiotherapy plan may be different from the plan parameters in the first radiotherapy plan.
Optionally, the detection device further includes a simulation calculation unit 103, where the simulation calculation unit 103 is configured to perform simulation calculation on plan parameter information in the second radiotherapy plan through a simulation algorithm, so as to obtain second dose distribution information corresponding to the second radiotherapy plan. Alternatively, after the second radiotherapy plan is saved to the detection means in the Dicom file format, the detection means may automatically perform a simulation calculation on the plan parameters using a simulation algorithm, thereby calculating the second dose distribution information. The simulation algorithm includes, but is not limited to, yu Mengte Carlo algorithm, pencil beam algorithm, CCC algorithm, AAA algorithm, AXB algorithm and the like. The Meng Ka algorithm (i.e. the monte carlo algorithm) is based on probability theory and physical statistics, and the energy value of the particles deposited in the substance is calculated by simulating the interaction process of a large number of particles (the particles comprise X-photons, electrons and the like) with the substance, namely, the transportation process of the particles, and the existing Meng Ka algorithm has huge calculation amount and complicated calculation steps, but compared with other algorithms, the Meng Ka algorithm has high calculation precision, so that the simulation algorithm in the application can be preferably Meng Ka algorithm, thereby ensuring the calculation precision of the second dose distribution information.
Optionally, the simulation algorithm in the application can also be an algorithm which is optimized to a certain extent on the basis of the existing Meng Ka algorithm, and the optimized algorithm can improve the calculation speed while ensuring the calculation precision.
Further, the detection device further includes a determining unit 104, where the determining unit 104 is configured to detect a similarity between the first dose distribution information and the second dose distribution information, and determine an actual execution condition of the target accelerator on the first radiotherapy plan according to the similarity.
It should be noted that, if the similarity between the first dose distribution information and the second dose distribution information is high, it is indicated that the actual execution state of the target accelerator on the first radiotherapy plan is good, and the target accelerator is equivalent to the dose distribution information (i.e., the first dose distribution information) expected to be achieved in the first radiotherapy plan is finally well achieved. However, if the similarity between the first dose distribution information and the second dose distribution information is low, this indicates that the actual execution state of the first radiotherapy plan by the target accelerator is poor, and the target accelerator does not well realize the dose distribution information expected to be reached in the first radiotherapy plan, that is, the target accelerator has a large deviation when executing the first radiotherapy plan.
In an alternative embodiment, the detection means may also display the first and second dose distribution information in various forms in the target display interface, for example in the form of DVH (Dose and Volume Histogram, dose volume histogram), or in the form of a graph, etc.
In addition, patient information of the target object, such as a CT image of the target object, a contour sketching image of a radiotherapy target area, a contour sketching image of a crisis organ, a pathological feature analysis result of the target object, and the like, can be displayed in the target display interface.
Further, the similarity and the difference information between the first dose distribution information and the second dose distribution information can be displayed in the target display interface, wherein when the difference between the first dose distribution information and the second dose distribution information exceeds the expected threshold value, corresponding prompt information is generated in the target display interface, so that a user or a manager of the target accelerator is prompted to check the target accelerator in time.
It should be noted that, by displaying the similarity and the difference information between the first dose distribution information and the second dose distribution information in the target display interface, the execution condition of the target accelerator on the radiotherapy plan is not required to be determined in a manual comparison mode, so that the detection efficiency of the execution condition of the accelerator on the radiotherapy plan is improved.
As can be seen from the above, the present application achieves the purpose of quickly determining the deviation between the actual irradiation dose (corresponding to the second dose distribution data) of the accelerator and the planned irradiation dose (corresponding to the first dose distribution data) in an automated manner by automatically acquiring the log file generated when the target accelerator executes the first irradiation dose and reversely generating a second irradiation dose corresponding to the target accelerator based on the log file, then calculating the actual irradiation dose distribution data (second dose distribution data) executed by the target accelerator in the actual irradiation process based on the plan parameter information in the second irradiation dose through a simulation algorithm, and finally improving the determination efficiency of the dose deviation and the detection efficiency of the execution status of the irradiation dose executing the accelerator by comparing the second dose distribution data with the first dose distribution data in the first irradiation dose plan.
Therefore, the technical scheme of the application achieves the purpose of shortening the deviation confirmation time of the actual irradiation dose and the planned irradiation dose, thereby solving the technical problem of low detection efficiency when the accelerator is checked to execute the execution condition of the radiotherapy plan in the prior art.
In an alternative embodiment, the acquisition unit further comprises: a data monitoring subunit and a data reading subunit.
Specifically, the data monitoring subunit is configured to monitor, when the target accelerator starts to execute the first radiotherapy plan, whether newly added data exists in a target folder through a target script, where the target folder is used to store log data generated by the target accelerator.
Alternatively, the target folder may be a folder corresponding to the target accelerator, for example, the target accelerator is accelerator a, the folder a-1 is used for storing log data generated by accelerator a, and the folder a-1 is the target folder corresponding to accelerator a.
In another alternative embodiment, the target folder may also be a plurality of folders corresponding to the target accelerator, for example, the target accelerator is accelerator B, and both the folder B-1 and the folder B-2 are used to store log data generated by accelerator B, so that both the folder B-1 and the folder B-2 are target folders corresponding to accelerator B.
In addition, the acquisition unit further comprises a data reading subunit, wherein the data reading subunit is used for reading the newly-added data in the target folder under the condition that the newly-added data exists in the target folder, and taking all the read newly-added data as file information of the log file after the target accelerator executes the first radiotherapy plan.
Further, the obtaining unit further includes a data processing subunit, where the data processing subunit is configured to prohibit reading of the data in the target folder when no newly added data exists in the target folder.
It should be noted that, the application can improve the reading efficiency of the log data by actively monitoring whether the target folder has new data, thereby ensuring that the latest log data generated by the target accelerator is read in time. Meanwhile, the method and the device can reduce labor cost and avoid missing log files caused by human negligence because the file folder is not required to be manually searched to obtain log data.
In an alternative embodiment, the parsing unit in the present application further includes: the system comprises a first acquisition subunit, an analysis subunit, an identification subunit and a plan generation subunit.
The first acquisition subunit is configured to acquire device information of the target accelerator, where the device information includes at least model information and manufacturer information of the target accelerator. And the analysis subunit is used for determining a log analysis algorithm corresponding to the target accelerator based on the equipment information, and analyzing the log file according to the log analysis algorithm to obtain an analysis result.
Alternatively, the file formats of the log files of the accelerators of different vendors or different models may be different, so that each vendor or model accelerator also corresponds to a unique log parsing algorithm. For example, the accelerator a is from the manufacturer 1, the accelerator B is from the manufacturer 2, the file format of the log file generated by the accelerator a is txt format, the file format of the log file generated by the accelerator B is xml format, on the basis that the log analysis algorithm corresponding to the accelerator a is txt file log analysis algorithm, and the log analysis algorithm corresponding to the accelerator B is xml file log analysis algorithm.
By acquiring the device information of the target accelerator and determining a log analysis algorithm corresponding to the target accelerator based on the device information, the success rate of log analysis can be improved.
In addition, the identifying subunit is configured to identify parameter information in the analysis result, where the parameter information includes at least patient information, radiation field information, and beam information according to which the target accelerator is executing the first radiotherapy plan.
It should be noted that, the patient information, the field information, and the beam information in the analysis result are parameter information used by the target accelerator in actual execution, and are not parameter information in the first radiotherapy plan that is directly taken, and there may be a difference between the two parameter information. In an ideal state, the parameter information actually executed by the target accelerator may be consistent with the parameter information in the first radiotherapy plan, but in actual operation, due to misoperation of a manager or a user of some target accelerators or machine errors of the target accelerator, the parameter information used by the target accelerator in actual execution has a certain deviation from the parameter information in the first radiotherapy plan.
And the plan generation subunit is used for generating a second radiotherapy plan according to the parameter information in the analysis result.
Specifically, the plan generation subunit may generate the second radiotherapy plan according to the patient information, the field information, the beam information, and the like related information in the analysis result.
In an alternative embodiment, the analog computation unit further comprises: the second acquisition subunit and the analog computation subunit.
The second acquisition subunit is configured to acquire a target image corresponding to the target object, where the target image at least includes a medical image corresponding to the target object, a contour sketch image of a radiotherapy target area of the target object, and a contour sketch image corresponding to a jeopardy organ of the target object. And the simulation calculation subunit is used for carrying out simulation calculation on the plan parameters in the second radiotherapy plan through a simulation algorithm according to the target image to obtain second dose distribution information corresponding to the second radiotherapy plan.
In particular, the simulation algorithms include, but are not limited to, yu Mengte Carlo algorithm, pencil beam algorithm, CCC algorithm, AAA algorithm, and AXB algorithm, among others.
When the simulation algorithm is used for performing simulation calculation on the plan parameters in the second radiotherapy plan, the detection device also needs to acquire a medical image corresponding to the target object, a contour sketch image of the radiotherapy target area and a contour sketch image corresponding to the organs at risk. The medical image may be a CT image, an MR image, or the like corresponding to the target object. The detection device can simulate and calculate the plan parameters in the second radiotherapy plan according to the medical image corresponding to the target object, the outline sketching image of the radiotherapy target area and the outline sketching image corresponding to the organs at risk by combining a simulation algorithm, so as to obtain second dose distribution information corresponding to the second radiotherapy plan.
In an alternative embodiment, the determining unit further comprises: the device comprises a detection subunit, a first determination subunit and a second determination subunit. The detection subunit is configured to detect whether the similarity is smaller than a preset threshold. And the first determination subunit is used for determining that the second dose distribution information is in a dose distribution deviation interval corresponding to the first dose distribution information and determining that the target accelerator normally executes the first radiotherapy plan under the condition that the similarity is greater than or equal to a preset threshold value. And a second determining subunit, configured to determine that the second dose distribution information is not in a dose distribution deviation interval corresponding to the first dose distribution information, and determine that the target accelerator does not normally execute the first radiotherapy plan, if the similarity is smaller than the preset threshold.
Alternatively, the preset threshold may be defined, which is not particularly limited in the present application, and for example, the preset threshold may be set to H1 for K kinds of cancer and to H2 for L kinds of cancer. Wherein H1 and H2 may be different.
Alternatively, if the similarity between the first dose distribution information and the second dose distribution information is greater than or equal to a preset threshold value, it is indicated that the second dose distribution information is within a dose distribution deviation interval corresponding to the first dose distribution information, wherein the dose distribution deviation interval may be understood as an error interval of the first dose distribution information set in advance. If the second dose distribution information actually generated by the target accelerator is located in the dose distribution deviation interval, the second dose distribution information is indicated to be acceptable to the object for making the first radiotherapy plan, and the deviation of the second dose distribution information is smaller than that of the first dose distribution information, so that the treatment effect on the target object is not excessively affected, and therefore the detection device can determine that the target accelerator normally executes the first radiotherapy plan.
However, if the second dose distribution information actually generated by the target accelerator is not within the dose distribution deviation interval, it is indicated that the second dose distribution information has a larger deviation than the first dose distribution information, which greatly affects the therapeutic effect on the target object, and the second dose distribution information is not acceptable to the object for which the first radiation plan is formulated, and therefore the detection device determines that the target accelerator does not normally execute the first radiation plan. It should be noted that, the dose distribution deviation interval may be set by the user of the subject who makes the first radiotherapy plan.
In an alternative embodiment, the apparatus for detecting an execution status of a radiotherapy plan further comprises: and an information generating unit. The information generating unit is used for generating prompt information according to the second dose distribution information and the similarity between the second dose distribution information and the first dose distribution information after the fact that the target accelerator does not normally execute the first radiotherapy plan is determined, wherein the prompt information is used for prompting a management object to detect the target accelerator, and the management object is the management target accelerator and/or an object using the target accelerator.
Optionally, when the target accelerator does not normally execute the first radiotherapy plan, a manager or a user of the target accelerator is required to first confirm the operation condition of the target accelerator, and then perform fault detection in time to ensure the subsequent normal use of the target accelerator.
It should be noted that, the form of the prompt information includes but is not limited to various forms such as text prompt, voice prompt, mail prompt, short message prompt, etc. The prompt information includes at least difference information between the first dose distribution information and the second dose distribution information in addition to information such as the second dose distribution information and the similarity between the second dose distribution information and the first dose distribution information.
By generating the prompt information, a manager or a user of the target accelerator can be timely reminded to conduct fault investigation on the target accelerator, and therefore the problem that the treatment effect of a target object is affected due to the fact that the fault of the target accelerator is not timely found can be avoided.
It should be noted that the detection device for executing the radiotherapy plan of the present application may also be used in a fault detection scenario for an accelerator.

Further, the apparatus for detecting an execution status of a radiotherapy plan further includes: a first data analysis unit, a second data analysis unit and a second transmission unit.
The first data analysis unit is used for carrying out data analysis on the first dose distribution information to obtain first analysis data corresponding to the first dose distribution information.
Optionally, the first analysis data at least includes dose volume histogram data corresponding to the first dose distribution information, gamma analysis data, dose data of the target region, and dose data of the crisis organ.
The first analysis data may include beam list information and clinical target information in the first radiotherapy plan, in addition to dose volume histogram data, gamma analysis data, dose data of the target region, and dose data of the critical organs corresponding to the first dose distribution information.

In an alternative embodiment, fig. 2 shows a flowchart of an alternative plan comparison according to an embodiment of the present application, as shown in fig. 2, a target accelerator generates a log file when executing a first radiotherapy plan, then a detection device reads the log file by monitoring a target folder in which the log file is located at a first time, the detection device converts the log file into a second radiotherapy plan by analyzing the log file, and the detection device invokes a simulation algorithm to calculate second dose distribution information corresponding to the second radiotherapy plan according to plan parameters in the second radiotherapy plan. Finally, the detection device compares the second radiotherapy plan with the first radiotherapy plan, wherein the similarity between the second dose distribution information and the first dose distribution information in the first radiotherapy plan is at least required to be compared in the comparison process.
It should be noted that, when the difference between the first dose distribution information and the second dose distribution information is clinically within an acceptable range, it is indicated that the current treatment can be continued; if the difference between the first and second dose distribution information is outside of a clinically acceptable range, it is necessary to check whether the target accelerator is normal, and thereby determine whether the target accelerator can be used to continue treatment of the patient.
As can be seen from the above, the present application achieves the purpose of quickly determining the deviation between the actual irradiation dose (corresponding to the second dose distribution data) of the accelerator and the planned irradiation dose (corresponding to the first dose distribution data) in an automated manner by automatically acquiring the log file generated when the target accelerator executes the first irradiation dose and reversely generating a second irradiation dose corresponding to the target accelerator based on the log file, then calculating the actual irradiation dose distribution data (second dose distribution data) executed by the target accelerator in the actual irradiation process based on the plan parameter information in the second irradiation dose through a simulation algorithm, and finally improving the determination efficiency of the dose deviation and the detection efficiency of the execution status of the irradiation dose executing the accelerator by comparing the second dose distribution data with the first dose distribution data in the first irradiation dose plan.
Therefore, the technical scheme of the application achieves the purpose of shortening the deviation confirmation time of the actual irradiation dose and the planned irradiation dose, thereby solving the technical problem of low detection efficiency when the accelerator is checked to execute the execution condition of the radiotherapy plan in the prior art.
