[0050] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0051] The serial numbers assigned to components in this article, such as "first" and "second", are used only to distinguish the objects being described and have no sequential or technical meaning.

[0052] First, before introducing the technical solutions of the embodiments disclosed in this application, the background technology or technological evolution on which the embodiments of this application are based will be introduced. In medical imaging examinations, when imaging a target object using various medical imaging technologies, it is necessary to emit radiation or inject tracers into the target object to perform imaging. Examples include radiotherapy, X-ray imaging, computed tomography (CT) imaging, positron emission tomography (PET) imaging, and PET-CT imaging. During the imaging process, the target object will be exposed to a certain dose of radiation. In traditional technologies, various medical imaging technologies usually record the radiation dose received by the target object during imaging or treatment through dose reports. However, currently, medical institutions only provide structured dose reports or dose reports for each target object, and do not make full use of these structured dose reports or dose reports. In response, this application provides a statistical analysis method.

[0053] The statistical analysis methods provided in this application can be applied to computer devices, including but not limited to industrial computers, laptops, and tablets. The internal structure of the computer devices can be as follows: Figure 1As shown, the computer device includes a processor, memory, communication interface, display screen, and input devices connected via a system bus. The processor provides computing and control capabilities. The memory includes non-volatile storage media and internal memory. The non-volatile storage media stores the operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs stored in the non-volatile storage media. The communication interface is used for wired or wireless communication with external terminals; wireless communication can be achieved through Wi-Fi, mobile cellular networks, NFC (Near Field Communication), or other technologies. When the computer program is executed by the processor, it implements a statistical analysis method. The display screen can be an LCD screen or an e-ink screen. The input devices can be a touch layer covering the display screen, buttons, a trackball, or a touchpad mounted on the computer device casing, or an external keyboard, touchpad, or mouse.

[0054] Those skilled in the art will understand that Figure 1 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the computer device to which the present application is applied. Specific computer devices may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0055] In one embodiment, such as Figure 2 As shown, a statistical analysis method is provided. This embodiment illustrates the application of this method to a computer device. In this embodiment, the method includes the following steps:

[0056] Step 200: Obtain multiple target dose reports; each target dose report includes information on the object being inspected, the items being inspected, and the equipment being inspected.

[0057] A target dose report is a report generated after a medical examination. It can include information about the examinee, the tests performed, and the equipment used. Examinee information refers to the examinee's identity, including name, gender, and age. Test information includes the name of the test, the protocols used, and dosages employed. Equipment information refers to the equipment used to perform the tests, including name and model. The target dose report may also include the test results. Multiple target dose reports can be multiple medical reports stored within a single medical institution, or multiple dose reports stored across multiple medical institutions. Multiple target dose reports can also represent multiple dose reports for the same test performed on the same examinee multiple times, multiple dose reports for the same test performed on different examinees, or multiple dose reports for different test performed on different examinees.

[0058] In an optional embodiment, the target dose report may include a structured dose report, or a dose report, or both a structured dose report and a dose report.

[0059] The computer device can acquire multiple target dose reports from the image equipment post-processing workstation or from servers such as PACS (Picture Archiving and Communication Systems). These multiple target dose reports can be pre-stored in the computer device's memory, and the computer device can retrieve them directly from the memory when needed. This embodiment does not limit the specific method for acquiring multiple target dose reports or the specific information included in the target dose reports, as long as the functionality is achieved.

[0060] Step 210: Perform statistical analysis on multiple target dose reports to determine the evaluation results; the evaluation results include at least one of the following: evaluation results on the examination dose, evaluation results on the examination effect, and evaluation results on the examination equipment.

[0061] After acquiring multiple target dose reports, the computer equipment performs statistical analysis on these reports to determine the evaluation results. In other words, it statistically analyzes the specific information included in each target dose report to assess the rationality of the examination dose and / or determine the optimal examination dose, thus obtaining an evaluation result for the examination dose. It can also evaluate the examination effect, obtaining an evaluation result for the examination effect, and further evaluate the performance of the examination equipment, obtaining an evaluation result for the examination equipment.

[0062] In an optional embodiment, for different evaluation results, corresponding evaluation models are pre-trained. After acquiring multiple target dose reports, the computer device inputs the target dose reports into the evaluation model. The evaluation model performs statistical analysis on the input target dose reports and can output the corresponding evaluation results.

[0063] The statistical analysis method provided in this application acquires multiple target dose reports; each target dose report includes information on the object being inspected, the inspection items, and the inspection equipment; statistical analysis is performed on the multiple target dose reports to determine the evaluation results; the evaluation results include at least one of the evaluation results on the inspection dose, the evaluation results on the inspection effect, and the evaluation results on the inspection equipment. In this embodiment, after acquiring multiple target dose reports, these reports are fully utilized to evaluate at least one of the inspection dose, the inspection effect, and the inspection equipment, thereby obtaining evaluation results. Furthermore, users can adjust the inspection dose or repair the inspection equipment based on the obtained evaluation results, thus utilizing the evaluation results obtained from the statistical analysis and improving the practicality of the statistical analysis method.

[0064] In one embodiment, such as Figure 3 As shown, one approach involves statistically analyzing multiple target dose reports to determine the evaluation results. The steps of this approach include:

[0065] Step 300: For each target dose report, extract the target information from the target dose report; the target information includes the inspection object information, inspection item information, and inspection equipment information.

[0066] After acquiring multiple target dose reports, the computer device extracts target information from each report. This target information may include information about the object being inspected, the items being inspected, and the equipment being inspected. A description of the specific information included in the target information can be found in the above embodiments and will not be repeated here.

[0067] In an optional embodiment, the target dose report includes a structured dose report. The structured dose report conforms to the DICOM (Digital Imaging and Communications in Medicine) standard, with different information having corresponding fields. The computer device extracts the target information by retrieving the fields corresponding to the desired target information from the target dose report. For example, for examination object information, the computer device can extract the target object's name by retrieving the "Name" field; and the target object's age by retrieving the "Age" field. For examination equipment information, the computer device can extract the equipment model from the target object's examination equipment information by retrieving the "Equipment Model" field. For examination item information, the computer device can extract the total radiation dose used in the examination item information by retrieving the "Total Dose" field.

[0068] In another alternative embodiment, the target dose report includes a dose report. The dose report is typically in image format. The computer device identifies the image corresponding to the dose report to obtain information from the dose report, and extracts the target information from the identified information.

[0069] Step 310: Perform statistical analysis on all target information to determine the evaluation results.

[0070] After extracting the target information from each target dose report, the computer device performs statistical analysis on all target information to determine the evaluation result. Different evaluation results require different methods for statistical analysis of all target information. If the evaluation result is an assessment of the examination effect, the computer device can obtain relevant information from all target information regarding multiple identical examinations of the same object and analyze it to obtain the corresponding evaluation result. This embodiment does not limit the specific method for statistical analysis of all target information to determine the evaluation result, as long as the function can be achieved.

[0071] In this embodiment, for each acquired target dose report, target information is extracted from the report; statistical analysis is performed on all target information to determine the evaluation result. This method of directly extracting target information from the target dose report for statistical analysis is quick and easy to implement, improving the efficiency of determining the evaluation result. Furthermore, when the target dose report includes a structured dose report, the standardized format of the structured dose report can improve the efficiency and accuracy of extracting target information from the report, thereby enhancing the accuracy and efficiency of determining the evaluation result.

[0072] In one embodiment, the evaluation results include an assessment of the examination dose, that is, an assessment of whether the radiation dose is appropriate when performing radiotherapy on the target subject. In this case, such as Figure 4 As shown, this involves statistical analysis of all target information to determine the evaluation results. The steps of this method include:

[0073] Step 400: Extract the first dose distribution information corresponding to the target object during a single target inspection from all target information.

[0074] The computer equipment extracts the first dose distribution information corresponding to a single target inspection of the target object from all acquired target information. The target object can be one or more of the inspection object information included in the target information. In other words, the computer equipment extracts the distribution information of the radiation dose applied to the target object during a single target inspection, i.e., the first dose distribution information. The first dose distribution information includes the total radiation dose applied to the target object during this target inspection, as well as the radiation dose applied to each tissue, organ, and target area.

[0075] Step 410: Based on the first dose distribution information, evaluate the rationality of the dose distribution to obtain the evaluation result of the examination dose.

[0076] After acquiring the first dose distribution information, the computer equipment assesses whether the radiation dose distribution applied to the target object during target inspection is reasonable, based on the first dose distribution information, and obtains the assessment result of the inspection dose. That is, it assesses whether the total radiation dose applied to the target object meets the actual requirements (will not cause harm to personnel), and whether the actual radiation dose to each tissue, organ, and target area within the target object meets the actual requirements (ensuring sufficient radiation to the target area while minimizing the radiation dose to organs and surrounding normal tissues). This embodiment does not limit the specific method for assessing the reasonableness of the dose distribution based on the first dose distribution information, as long as the function can be achieved.

[0077] In an optional embodiment, there are corresponding reasonableness thresholds for the total radiation dose and the radiation dose of each tissue / organ and target area. After obtaining the first dose distribution information, the computer device compares the total radiation dose in the first dose distribution information with the corresponding reasonableness threshold, and compares the radiation dose of each tissue / organ and target area with the corresponding reasonableness threshold, thereby assessing the reasonableness of the dose distribution and obtaining the assessment result of the examination dose.

[0078] In this embodiment, by extracting the first dose distribution information corresponding to a single target inspection of the target object from all target information, and evaluating the rationality of the dose distribution based on the first dose distribution information, an evaluation result of the inspection dose is obtained. Thus, by using the first dose distribution information extracted from all target information from multiple target dose reports, the rationality of the dose distribution can be evaluated, and an evaluation result of the inspection dose can be obtained. This enables full utilization of target dose reports and improves the practicality of statistical analysis methods.

[0079] In one embodiment, after the computer device extracts first dose distribution information from all target information and obtains an evaluation result of the examination dose based on the first dose distribution information, the method further includes:

[0080] The first dose distribution information is displayed on the display interface, and different identifiers are used to characterize the rationality of the dose distribution.

[0081] The computer device includes a display screen on which a display interface is displayed. After obtaining the first dose distribution information, the computer device can display this information on the display interface. Specifically, the display interface shows a human model of the target object, and the first dose distribution information is displayed on the corresponding tissues, organs, and target areas within the human model. Furthermore, different identifiers can be used when displaying the first dose distribution information to indicate the appropriateness of the dose distribution for different tissues, organs, and target areas. In other words, different identifiers can be used to represent different tissues, organs, and target areas of the target object, and also to indicate the appropriateness of the dose distribution for different tissues, organs, and target areas.

[0082] In an optional embodiment, the first dose distribution information is displayed on the display interface as follows: Figure 5 As shown, Figure 5 Different colors represent the appropriateness of dose distribution in different tissues, organs, and target areas. The appropriateness threshold for dose distribution varies for different tissues, organs, and target areas, and the corresponding color indicates when the dose distribution reaches this threshold. For example, blue can be used to represent the appropriateness threshold for the head, while green can be used for the legs.

[0083] In this embodiment, by displaying the first dose distribution information on the display interface and using different identifiers to characterize the rationality of the dose distribution, it is convenient for users to clearly obtain the dose distribution of each tissue and organ of the target object and the target area, as well as whether the dose is reasonable, which can improve the practicality and reliability of the statistical method.

[0084] In one embodiment, the evaluation results include an evaluation of the examination effect, that is, an evaluation of the radiotherapy effect on the target subject. In this case, as in... Figure 6 As shown, this involves statistical analysis of all target information to determine the evaluation results. The steps of this method include:

[0085] Step 600: Extract multiple second dose distribution information corresponding to the target object from all target information and perform multiple target checks.

[0086] The computer device extracts the second dose distribution information corresponding to multiple target checks performed on the target object from all acquired target information. That is, the computer device extracts the radiation dose distribution information applied to the target object during the first target check (i.e., the first second dose distribution information); the radiation dose distribution information applied to the target object during the second target check (i.e., the second second dose distribution information); the radiation dose distribution information applied to the target object during the third target check (i.e., the third second dose distribution information), and so on, thus obtaining multiple second dose distribution information. The description of the second dose distribution information can be referred to the specific description of the first dose distribution information in the above embodiments, and will not be repeated here.

[0087] Step 610: Based on multiple second dose distribution information, evaluate the examination effect of the target examination to obtain the evaluation result of the examination effect.

[0088] After obtaining multiple second dose distribution information, the computer equipment comprehensively analyzes the dose distributions within these multiple second dose distribution information to evaluate the effectiveness of target examinations on the target subject, i.e., to assess the effectiveness of radiotherapy on the target subject, and obtain an evaluation result of the examination effect. In other words, it assesses whether the target subject's symptoms have been relieved after multiple target examinations using multiple second dose distribution information.

[0089] In this embodiment, multiple second dose distribution information corresponding to multiple target inspections of the target object is extracted from all target information. Based on these multiple second dose distribution information, the inspection effect of the target inspection is evaluated, and the evaluation result is determined. By statistically analyzing the multiple second dose distribution information extracted from all target information from multiple target dose reports, the inspection effect of the target inspection can be evaluated, thereby fully utilizing the target dose reports and improving the practicality of the statistical analysis method. Furthermore, the evaluation result obtained by evaluating the inspection effect of the target inspection can assist users in developing inspection plans for the target object, further enhancing the practicality of the statistical analysis method.

[0090] In one embodiment, such as Figure 7 As shown, this relates to an implementation method for evaluating the examination effect of a target examination based on multiple second dose distribution information, and obtaining an evaluation result of the examination effect. The steps of this implementation method include:

[0091] Step 700: Display multiple second dose distribution information on the display interface.

[0092] After obtaining multiple second dose distribution information, the computer device displays the multiple second dose distribution information on the display screen. A description of displaying multiple second dose distribution information can be found in the detailed description of displaying the first dose distribution information in the above embodiments, and will not be repeated here.

[0093] In an optional embodiment, multiple second dose distribution information sets can be displayed on the same display interface, or different second dose distribution information sets can be switched on a single display interface through user operation. For example, the corresponding second dose distribution information sets can be displayed sequentially according to the examination order on the same display interface. Figure 8 As shown, the display interface shows the second dose distribution information corresponding to the first and second target checks of the target object, from left to right. Alternatively, the display interface can show the second dose distribution information corresponding to the first target check, or, in response to the user's switching operation, the display interface can show the second dose distribution information for any target check selected by the user. For example... Figure 9 As shown, the display interface shows the second dose distribution information corresponding to the first target check. The computer device responds to the user's switching operation, such as... Figure 10 As shown, the second dose distribution information corresponding to the second target check is displayed on the display interface, that is, the second dose distribution information corresponding to the first target check is replaced by the second dose distribution information corresponding to the second target check.

[0094] Step 710: In response to the user's confirmation of multiple second dose distribution information, determine the evaluation result of the examination effect.

[0095] After displaying multiple second dose distribution information on the interface, the user observes and analyzes this information to evaluate the effectiveness of the target examination (i.e., the examination result). The computer device responds to the user's confirmation operation and determines the evaluation result of the examination result. The confirmation operation can be a click or drag operation of the confirmation control on the display interface, or it can be an input operation where the user enters their evaluation result of the examination result on the display interface.

[0096] In an optional embodiment, a first control indicating a better inspection result and a second control indicating a worse inspection result are displayed on the display interface. If the user clicks the first control, the computer device responds to the click and determines that the inspection result is better; if the user clicks the second control, the computer device responds to the second click and determines that the inspection result is worse.

[0097] In an optional embodiment, an inspection effect input box is displayed on the screen. The user observes and analyzes multiple second dose distribution information and enters the user's evaluation result of the inspection effect in the inspection effect input box; the computer device responds to the user's input operation and obtains the evaluation result of the inspection effect.

[0098] In this embodiment, by displaying multiple second dose distribution information on the display interface, and responding to the user's confirmation operation on the multiple second dose distribution information, the evaluation result of the examination effect is determined. This allows the user to clearly and explicitly obtain the dose distribution of each tissue, organ, and target area of ​​the target object during multiple target examinations, thereby enabling the user to more accurately evaluate the examination effect. Furthermore, based on the obtained evaluation result of the examination effect, the user can be instructed to adjust the next examination of the target object, which can improve the practicality and reliability of the statistical method.

[0099] In one embodiment, where the evaluation results include an evaluation of the examination dose, such as Figure 11 As shown, another approach to determining the evaluation results involves statistical analysis of all target information. This approach includes the following steps:

[0100] Step 111: Extract multiple third dose distribution information corresponding to the target inspection of multiple target objects from all target information.

[0101] The computer device extracts multiple third dose distribution information of multiple target objects from all acquired target information. In other words, it extracts the third dose distribution information corresponding to multiple target objects undergoing the same target examination. The description of the third dose distribution information can refer to the specific description of the first dose distribution information in the above embodiments, and will not be repeated here. Multiple target objects can refer to multiple objects of different age groups or multiple objects of different genders; this embodiment does not impose any restrictions, as long as the function can be achieved.

[0102] Step 112: Based on multiple third dose distribution information, evaluate the target dose corresponding to the target examination to obtain the evaluation result of the examination dose.

[0103] After acquiring multiple third-dose distribution information, the computer device performs statistical analysis on these distributions to determine the target dose (optimal dose) for the target examination. This involves evaluating the target dose corresponding to the target examination and obtaining an assessment result. If the multiple third-dose distribution information refers to multiple third-dose distributions corresponding to multiple subjects of different age groups, the computer device can determine the target dose for target examinations of target subjects of different age groups through statistical analysis. Similarly, if the multiple third-dose distribution information refers to third-dose distributions of different genders, the target dose for target examinations of target subjects of different genders can be determined through statistical analysis.

[0104] In this embodiment, multiple third dose distribution information corresponding to the target inspection of multiple target objects is extracted from all target information; the target dose corresponding to the target inspection is evaluated based on the multiple third dose distribution information to determine the evaluation result of the inspection dose. In this way, by using multiple third dose distribution information extracted from all target information from multiple target dose reports, the target dose corresponding to the target inspection can be evaluated, and the evaluation result of the inspection dose can be obtained. This enables full utilization of the target dose reports and improves the practicality of the statistical analysis method. Furthermore, the evaluation result of the target dose corresponding to the target inspection can assist the user in setting the irradiation dose when performing target inspections on the object to be inspected, further enhancing the practicality of the statistical analysis method.

[0105] In an optional embodiment, the computer device can determine the most frequently used dose as the target dose by analyzing multiple third dose distribution information obtained.

[0106] In another optional embodiment, after obtaining multiple third dose distribution information and performing statistical analysis on them, the computer device can display the dose distribution information corresponding to multiple target objects on a display interface, i.e., multiple third dose distribution information. Specifically, if the multiple target objects can be multiple objects of different age groups, a graph can be used to display the dose distribution information corresponding to the multiple target objects, with the horizontal axis representing the age group of the target objects and the vertical axis representing the dose. In response to the user's confirmation operation on the multiple third dose distribution information, the computer device determines the target dose corresponding to the target examination, i.e., obtains the evaluation result of the examination dose.

[0107] In one embodiment, the evaluation results include evaluation results of the inspection equipment, that is, an evaluation of the inspection equipment used when performing target inspection on the target object. In this case, such as Figure 12 As shown, one approach involves statistically analyzing all target information to determine the evaluation results. This approach includes:

[0108] Step 121: Extract multiple fourth dose distribution information of the target object from all target information, which are the target objects being inspected on multiple inspection devices.

[0109] The computer device extracts multiple fourth dose distribution information corresponding to the target object when it is inspected on multiple inspection devices from all acquired target information. Each inspection device corresponds to one fourth dose distribution information. The description of the fourth dose distribution information can be referred to the specific description of the first dose distribution information in the above embodiments, and will not be repeated here.

[0110] Step 122: Based on multiple fourth dose distribution information, evaluate the performance of the examination equipment to obtain the evaluation results of the examination equipment.

[0111] After obtaining multiple fourth dose distribution information, the computer device performs statistical analysis on the multiple fourth dose distribution information to evaluate the performance of multiple inspection devices used when inspecting the target object. That is, it evaluates the operation of the inspection devices when inspecting the target, as well as the time consumption, efficiency and power consumption of the inspection devices, and obtains the evaluation results of the inspection devices.

[0112] In this embodiment, multiple fourth dose distribution information of the target object underwent target inspection on multiple inspection devices by extracting all target information; the performance of the inspection devices is evaluated based on the multiple fourth dose distribution information to determine the evaluation result of the inspection devices. By statistically analyzing the multiple fourth dose distribution information extracted from all target information from multiple target dose reports, the performance of the inspection devices can be evaluated, thereby fully utilizing the target dose reports and improving the practicality of the statistical analysis method. Furthermore, the evaluation result of the inspection device performance evaluation can assist users in maintaining the inspection devices, further enhancing the practicality of the statistical analysis method.

[0113] In one embodiment, the statistical analysis method further includes:

[0114] In response to user queries, target dose statistics are displayed on the interface. The query is determined based on preset query dimensions, which include the object of inspection and the items to be inspected.

[0115] The preset query dimensions can be pre-set by the user according to actual needs. Preset query dimensions can include the examination object and examination items. Users can query by examination object, for example, a user can query the dosage information of examination objects in a target age group; they can also query by examination items, for example, a user can query the dosage information of examination items for the abdominal region; or they can query by a combination of examination object and examination items, for example, a user can query the dosage information of examination objects for the target age group in the abdominal region examination. This embodiment does not limit the preset query dimensions, as long as the function can be achieved.

[0116] Users perform queries on the display interface according to their actual needs, that is, they input or select the target query dimension on the display interface. The computer device responds to the query operation and displays the target dose statistics corresponding to the query operation on the display interface, that is, the dose statistics found according to the target query dimension. The target dose statistics can be displayed on the display interface using different types of statistical charts, such as pie charts, bar charts, sector charts, and column charts. This embodiment does not limit the way the target dose statistics are displayed on the display interface, as long as the function is achieved.

[0117] In an optional embodiment, such as Figure 13 As shown, a pie chart provides target dose statistics for different query dimensions. Figure 13 The first graph shows the distribution of target dose statistics for users of different genders when the query dimension is user gender; the second graph shows the distribution of target dose statistics for different device types when the query dimension is device type; and the third graph shows the distribution of target dose statistics for different scanning sites when the query dimension is scanning site.
