[0056] The present application is further described below by way of examples, but the present application is not limited to the scope of the examples.

[0057] In the description of this application, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0058] Example 1

[0059] This embodiment provides a control method for a medical scanning system. Figure 1 As shown, the control method includes:

[0060] S101, obtaining historical inspection information of the object to be scanned;

[0061] S102, in response to the historical examination information including a historical scan image, obtaining a first working parameter of the medical scanning system corresponding to the historical scan image;

[0062] S103, adjusting a second working parameter of the current medical scanning system based on the first working parameter, and scanning the object to be scanned based on the second working parameter to obtain a current scanned image;

[0063] The image quality parameters of the current scanned image and the historical scanned image are matched.

[0064] In this solution, by acquiring historical detection information of the object to be scanned, the image parameters of the current scan are matched based on the image quality parameters of the same modality image examination in the historical detection; illustratively, the same modality image examination includes but is not limited to CT (Computed Tomography) examination and PET examination. This makes the image quality of the current scan image consistent with that of the historical examination image, improves the detection efficiency, filters the interference caused by the image quality for subsequent image analysis, and ensures the readability and accuracy of the scanned image.

[0065] As an implementable manner, step S101 includes:

[0066] Acquiring identification information of the object to be scanned;

[0067] Identify the identity information of the object to be scanned based on the identification information, and acquire the corresponding historical inspection information based on the identity information;

[0068] As an implementable manner, the historical examination information includes historical vital sign information and corresponding first scanning parameters, and the control method further includes:

[0069] Get current vital signs information;

[0070] Based on the change between the historical vital sign information and the corresponding current vital sign information, the first scanning parameter is adjusted to obtain a second scanning parameter for the current scan of the scan object.

[0071] In this solution, the corresponding identity information and historical scanned images are matched based on the identification information of the object to be scanned; exemplarily, the identification information includes fingerprint information, facial recognition information, and identity coding information, etc. The corresponding acquisition method can obtain facial recognition information and identity coding information through image recognition, and obtain fingerprint information through at least one of optical recognition, capacitive recognition and ultrasonic recognition; accurate matching of historical inspection information is achieved through at least one identification information to ensure the security of user privacy data.

[0072] On the other hand, by obtaining the current vital sign information within the preset inspection period before the current scan, and comparing it with the vital sign information corresponding to the historical scan image, the current first scan parameter is adjusted based on the vital sign difference information obtained after the comparison; illustratively, the corresponding injection type, dosage and rest time in the historical scan image are obtained based on the historical inspection information, and the injection and rest time corresponding to the current inspection are calculated according to the changes in vital signs from the historical inspection to the current inspection of the object to be scanned, and the corresponding first recommended working parameters are obtained. Exemplarily, the vital sign information includes at least one of body weight, the part to be scanned and the thickness of the part to be scanned, and corresponding adjustments can also be made based on the disease progression or lesion changes corresponding to the object to be scanned, so as to realize the adaptive adjustment of the scanning parameters of different objects to be scanned by the medical scanning system, ensure the image quality of the scanned image, and accurately control the radiation dose of the object to be scanned.

[0073] As an implementable manner, the historical examination information includes historical body position information, and the control method further includes:

[0074] Get current body position information;

[0075] In response to the current body position being different from the historical body position, a prompt for body position adjustment is sent to the object to be scanned.

[0076] In this solution, the body position information of the object to be scanned at the time of the current scan is obtained and compared with the historical body position information corresponding to the historical scan image, so as to prompt the object to be scanned to present a body position consistent with the historical body position information. Exemplarily, a body position model of the object to be scanned is generated through the historical scan image, and the current body position of the object to be scanned is matched based on the body position model. It is also possible to generate a number of regions of interest in the body position model based on the anatomical structure of interest, and match the position information of the regions of interest with the corresponding positions in the current body position of the object to be scanned. In the case that the current body position is inconsistent with the historical body position, at least one of voice prompts, animation prompts and light prompts is used to guide the object to be scanned to adjust its body position, so as to achieve consistency between the current scanned body position and the historical body position, ensure that the image quality of the scanned image obtained by the medical scanning system is consistent with that of the historical scanned image, and achieve adaptive adjustment of the medical scanning system.

[0077] As a feasible approach, Figure 2 As shown, the step of adjusting the second working parameter of the current medical scanning system based on the first working parameter in step S103 includes:

[0078] S1031, obtaining a first quality parameter of the historical scanned image;

[0079] S1032, acquiring a first recommended operating parameter of the current medical scanning system according to the first operating parameter, and acquiring a second quality parameter of the inferred scanned image obtained by scanning based on the first recommended operating parameter;

[0080] S1033. In response to the second quality parameter being inconsistent with the first quality parameter, adjusting the first recommended operating parameter to make the second quality parameter consistent with the first quality parameter;

[0081] S1034: In response to the second quality parameter being consistent with the first quality parameter, using the first recommended operating parameter as the second operating parameter.

[0082] In this solution, the image quality parameters of the estimated image are compared with those of the historical scanned image by estimating the current recommended working parameters of the medical scanning system; illustratively, the first recommended working parameters are obtained based on the historical scanned image's historical scanned parameters, the historical scanned parameters include but are not limited to the scanned protocol, the scanned part, the scanned time or the reconstruction parameters, etc., the estimated scanned image is obtained by the first recommended working parameters, and the image quality parameters are compared based on the image signal-to-noise ratio and / or contrast corresponding to the estimated scanned image and the historical scanned image. This is to adjust the current recommended parameters, ensure that the image quality of the scanned image obtained by the medical scanning system is consistent with that of the historical scanned image, and realize the adaptive adjustment of the medical scanning system.

[0083] As an achievable manner, the control method further includes:

[0084] In response to the historical inspection information not including the historical scan image, the historical inspection information is input into a pre-trained scan parameter model, and a second recommended working parameter is obtained based on the scan parameter model output;

[0085] The object to be scanned is scanned based on the second recommended working parameter to obtain a current scanned image.

[0086] In this scheme, for the first scan of the object to be scanned, the historical examination information of the object to be scanned is input into the pre-trained scanning parameter model to obtain the second recommended working parameter suitable for the object to be scanned; illustratively, according to the text data and / or image data in the historical examination information of the object to be scanned, the first feature about the part to be scanned is identified and analyzed, and the second feature of the description of the condition of the object to be scanned is obtained through voice recognition in combination with the main complaint of the object to be scanned, and the relevant examination of the part to be scanned required by the object to be scanned is obtained through the pre-trained scanning parameter model based on the first feature and / or the second feature as input; for example: if the part to be scanned is the lung, then on the basis of the PET / CT whole-body tumor examination, the scanning time of the lung is increased, or the lung is scanned with breath holding, or a lung thin-layer CT is added, etc., and the reconstruction algorithm for lung respiratory artifact correction is selected in the reconstruction parameters, so as to ensure that the imaging can meet the doctor's diagnostic needs for lung diseases. The automatic generation of working parameters of the medical scanning system is realized, or the corresponding recommended working parameters are generated, and the pre-setting of the scanning work is completed for the user, thereby improving the working efficiency of the medical scanning system.

[0087] As an achievable method, the historical examination information includes lesion information, such as Figure 3 As shown, the control method also includes:

[0088] S104, identifying a target lesion region in the current scanned image based on the lesion information, and segmenting the current scanned image to obtain a target lesion image;

[0089] S105: Generate an inspection report based on the target lesion image and the historical inspection information.

[0090] In this scheme, the lesion information in the historical examination information is used to accurately segment the corresponding target lesion image from the current scanned image, and a corresponding inspection report is generated based on the target lesion image and the historical examination information, thereby improving the readability of the scanned image and increasing the effective information density in the inspection report.

[0091] As a feasible approach, Figure 4 As shown, step S105 includes:

[0092] S1051, inputting the target lesion image into a pre-trained lesion recognition model, and outputting a target recognition result of the target lesion area;

[0093] S1052: Generate the inspection report using the target lesion image, target recognition result and historical inspection information.

[0094] In this scheme, automatic recognition of the target lesion image is achieved through a pre-trained lesion recognition model, and the corresponding lesion recognition result is output based on the recognition result; illustratively, the lesion recognition result includes but is not limited to the type of lesion, the size of the lesion area or the SUV (Standard Uptake Value) value of the lesion, and the lesion recognition result is generated into text as part of the inspection report, thereby improving the readability of the scanned image and increasing the effective information density in the inspection report.

[0095] As a feasible approach, Figure 5 As shown, step S105 includes:

[0096] S1053, in response to the historical examination information including the historical scan image, identifying a historical lesion area in the historical scan image;

[0097] S1054, obtaining lesion change information based on the historical lesion area and the target lesion area;

[0098] S1055. Generate the inspection report based on the target lesion image, lesion change information and historical inspection information.

[0099] In this solution, the target lesion image obtained by the current scanned image is compared with the historical lesion area to obtain the lesion change information of the lesion area of ​​the scanned object, and the lesion change information includes but is not limited to the size change or SUV value change of the lesion area; illustratively, the lesion change information can be compared with the reference change information corresponding to the lesion to obtain the evaluation result of the lesion change information; or, the lesion change information is input into a pre-trained lesion prediction model to output the corresponding evaluation result of the lesion change information. The lesion change information and its evaluation results, historical inspection information and the target lesion image are used to generate an inspection report, thereby improving the readability of the scanned image and increasing the effective information density in the inspection report.

[0100] The working principle of the control method of the medical scanning system of the present application is described in detail below with reference to examples:

[0101] First, confirm the identity of the person being inspected and whether it is the first time for the person to be inspected;

[0102] Confirm the identity of the person being inspected through unique identification codes such as fingerprints, facial recognition, ID (Identity Document, identity information) etc.

[0103] Retrieve all the examinee's previous historical examination information, including but not limited to electronic information, imaging materials, text reports and other information that have been recorded in the hospital information system; extract the examinee's diagnostic information through natural language processing and text recognition technologies; analyze the examinee's chief complaint information based on speech recognition technology to confirm whether this is the examinee's first examination.

[0104] If the person being examined confirms that this is the first examination, the system will intelligently recommend scanning and reconstruction parameters that meet the examination requirements, including information such as the injection type, dosage, and resting time in the PET examination.

[0105] If the examinee is confirmed as a follow-up examinee, the examinee's past examination images are obtained, and scanning and reconstruction parameters suitable for follow-up analysis are recommended based on preset recommendation rules.

[0106] Before scanning, the injection type, dosage, and rest time of previous scans are obtained based on the images. The injection and rest time required for this examination are estimated based on the changes in the examinee's physical condition between the last examination and this examination.

[0107] Based on the image, the subject's previous examination position information is extracted, and a body position model diagram of the subject can be generated based on the image to guide the subject's current scanning position and ensure the consistency of the position of the two scans. Among them, image acquisition includes but is not limited to medical images collected by single-modality CT equipment, PET (Positron Emission Computed Tomography) equipment, MRI (Magnetic Resonance Imaging) equipment, multi-modality PET / CT equipment, PET / MR equipment, etc.

[0108] Extracting scanning parameters of previous examinations based on images, including but not limited to scanning protocols, locations, time, and reconstruction parameters, etc., to recommend scanning and reconstruction for this examination;

[0109] Based on the image intelligence, the image quality parameters of previous examinations are analyzed to determine whether the parameters recommended for this examination can meet the image quality consistency of previous examinations;

[0110] The image quality of this examination is estimated based on the recommended injection and rest time, as well as the recommended scanning and reconstruction parameters. The image quality of the estimated image is compared with the image quality of the historical examination. If the image quality of the two is consistent, the scan is started. If the image quality of the two is inconsistent, the scanning and reconstruction parameters of this examination are adjusted according to the difference in image quality, thereby improving the consistency of image quality between the two examinations.

[0111] Scanning and reconstruction are performed based on the final recommended parameters to obtain the scanned image of this examination;

[0112] Perform intelligent analysis on the acquired images and output graphic reports.

[0113] For the first-time examinee, the medical history information section of the report is generated intelligently based on the diagnosis and medical history information of the examinee that has been obtained; based on the obtained imaging information, the suspected lesion area is intelligently detected and segmented, and text descriptions are added, and screenshots are used for graphic reports; based on the suspected lesion area obtained by intelligent segmentation, the examinee's condition is evaluated, and combined with medical history and other information, a preliminary diagnosis conclusion is formed, and a graphic report is formed;

[0114] For the follow-up examinees, the images of the two examinations are compared, and the lesion areas are identified and segmented from the two examination images according to the preset segmentation rules, and the consistency of the two scanned images is ensured in the scanning workflow to effectively compare and analyze the two images. Screenshots and text descriptions are taken for the lesion areas of the two images respectively, and the changes in the same lesion area in the two scans are compared, such as changes in lesion volume and SUV value, so as to evaluate the progression of the examinee's condition, form a preliminary diagnosis, and finally form a graphic report.

[0115] The control method of the medical scanning system provided in the present embodiment realizes the automatic adjustment of the current working parameters of the medical scanning system based on the historical inspection information of the object to be scanned through the automated workflow, so as to make the image quality of multiple scanned images of the object to be scanned consistent, simplify the user's operation process, and improve the accuracy of the scanned image; by segmenting, identifying and comparing the lesion image in the current scanned image, the corresponding target lesion image, lesion change information and lesion evaluation results are obtained, and the lesion change information and its evaluation results, the historical inspection information and the target lesion image are generated into an inspection report, thereby improving the readability of the scanned image and increasing the effective information density in the inspection report.
