[0002] Medical site examination has evolved from empirical judgment to scientific and precise methods, and has now become an indispensable diagnostic and treatment tool in clinical practice. Its development can be traced back to ancient intuitive diagnosis. Later, breakthroughs in microscopy, automated equipment, and molecular biology technologies have gradually led to the segmentation and intelligentization of testing items. The widespread adoption of technologies such as fully automated analyzers and genetic testing has driven the rise of personalized medicine and remote testing. Medical site examination is widely used for disease diagnosis (such as CT diagnosis of early lung cancer), disease assessment (cardiac ultrasound to observe cardiac structure), screening and prevention (low-dose CT lung cancer screening), treatment monitoring (real-time imaging of interventional treatments), and disease staging (CT / MRI tumor staging), providing comprehensive clinical support.

[0055] The present invention discloses a method and intelligent system for multi-part identification based on RAG optimization of a large medical model. Those skilled in the art can refer to the content of this article and appropriately improve the technical details. It should be pointed out in particular that all similar replacements and modifications are obvious to those skilled in the art and are considered to be included in the present invention. The method and application of the present invention have been described through preferred embodiments. Relevant personnel can obviously modify or appropriately change and combine the methods and applications described herein without departing from the content, spirit and scope of the present invention to implement and apply the technology of the present invention.

[0056] The imaging cloud platform is unable to accurately identify the number and name of each part examined, leading to difficulties in imaging data management, a lack of innovation in project operation models, and difficulty in implementing cross-institutional imaging sharing and mutual recognition. Artificial intelligence can be used to standardize chaotic data, but existing AI recognition technology cannot accurately identify specific data from individual medical institutions, resulting in low recognition accuracy.

[0057] Therefore, the present invention provides a multi-site identification method based on RAG optimization of a large medical model, which is used for the collection and management of medical data of medical institutions on different imaging cloud platforms, such as Figure 1 As shown, the method includes:

[0058] Step S1: Receive first medical examination data to be collected from a first medical institution.

[0059] The first medical examination data is multimodal data including at least corresponding text data and image data. The first medical institution is a medical institution to be data collected among multiple medical institutions on different image cloud platforms.

[0060] In this specific embodiment, in step S1 , data of multiple modalities of the first medical examination data are transmitted separately or in mixed and coordinated manner.

[0061] It should be noted that the input channels mainly include the following: text processing channel: supports free text input (including electronic medical record text, examination application form, etc.); image processing channel: compatible with DICOM / JPEG / PNG format image input; mixed input mode: allows collaborative text input of images to improve recognition confidence.

[0062] After step S1, the method further includes step S1A:

[0063] Obtaining first patient information corresponding to the first medical examination data; obtaining historical medical examination data of the first patient based on the first patient information;

[0064] In response to the existence of second medical examination data in the historical medical examination data, the time difference between the first medical examination data and the first medical examination data and the same examination site as the first medical examination data does not exceed a first threshold, obtaining the second medical examination data;

[0065] In response to the fact that the level of the second medical institution corresponding to the second medical examination data is greater than the level of the first medical institution, the first medical examination correction data corresponding to the first medical examination data and conforming to the data standardization specifications are output according to the writing specifications of the second medical examination data and input into step S2 for processing as the first medical examination data.

[0066] It should be noted that, through the processing of step S1A, the first medical examination data can be corrected according to the data specifications of a higher-level medical institution, so that the corrected first medical examination data is more standardized, thereby improving its recognition accuracy in subsequent steps.

[0067] In this specific embodiment, step S1A further includes:

[0068] Acquire first medical examination data and second medical examination data having a time difference of no more than a first threshold and the same examination site as the first medical examination data, and construct a data pair set of the first medical examination data and the second medical examination data;

[0069] Based on the image data in the data pair set, an image data correction model is trained to determine the correspondence between the first medical examination data and the second medical examination data; the image data correction model is used to autonomously generate second mirror medical examination data corresponding to the first medical examination data of the first medical institution and the writing standards of the second medical institution, and is used for aggregation and as the first medical examination data to execute subsequent steps.

[0070] It should be noted that through model training, a correspondence can be established between the medical examination data of low-level medical institutions and the medical examination data of high-level medical institutions, and then the medical examination data of low-level medical institutions can be corrected according to the relationship, so that the recognition accuracy of the medical examination data of low-level medical institutions in subsequent steps can be higher.

[0071] In this specific embodiment, in response to the presence of second medical examination data in the historical medical examination data, which has a time difference of no more than a first threshold with respect to the first medical examination data and has the same examination site as the first medical examination data, before obtaining the second medical examination data, the method includes:

[0072] Extracting features corresponding to the first medical examination data and the historical medical examination data respectively, and obtaining examination parts corresponding to the first medical examination data and the historical medical examination data;

[0073] According to the examination parts corresponding to the first medical examination data and the historical medical examination data, second medical examination data with a time difference of no more than a first threshold and the same examination part as the first medical examination data is obtained.

[0074] It should be noted that this embodiment is intended to ensure that the first medical examination data and the second medical examination data are examination data of the same part within the same time period, so as to avoid correction errors caused by mismatching, thereby affecting subsequent recognition.

[0075] Step S2: Determine whether there is a first identification parameter corresponding to the first medical institution. If so, perform data preprocessing and part feature extraction on the first medical examination data based on the first identification parameter to obtain the part identification feature of the first medical examination data; if not, perform data preprocessing and part feature extraction on the first medical examination data based on the standard identification parameter to obtain the part identification feature of the first medical examination data.

[0076] Among them, the first recognition parameter is obtained through pre-training of the medical examination data set of the first medical institution, and the recognition parameters obtained by training in different medical institutions are different. The first recognition parameter is used to improve the model recognition accuracy based on the writing standards and inspection equipment differences of different medical institutions; the standard recognition parameter is obtained by mixed training of the general medical examination data set; the part recognition features include part recognition text features and part recognition image features.

[0077] It should be noted that conventional medical examination data is typically identified based on standard recognition parameters, rarely specifically addressing differences in documentation and equipment between different medical institutions, resulting in low recognition accuracy. However, the present invention uses separate training to obtain recognition parameters corresponding to different medical institutions, and then identifies the corresponding medical data based on these recognition parameters. This improves model recognition accuracy by addressing differences in documentation standards and examination equipment across different medical institutions.

[0078] In this specific embodiment, in step S2, the method further includes:

[0079] In response to the absence of a first identification parameter corresponding to the first medical institution, extracting common features from the medical examination dataset from the first medical institution; wherein the common features include at least text word usage features, text format features, examination equipment model features, and image clarity features;

[0080] Training is performed based on the common features to obtain the first recognition parameters.

[0081] It should be noted that this embodiment can perform feature extraction training on medical data from medical institutions that do not have existing identification parameters, thereby obtaining corresponding identification parameters to improve the accuracy of subsequent medical data recognition. This embodiment obtains identification parameters through training on continuously accumulated medical data, thereby making the identification parameters more reliable.

[0082] In this specific embodiment, the data preprocessing of the first medical examination data in step S2 includes:

[0083] Noise filtering is performed on the text data in the first medical examination data; and a corresponding processing method is selected according to the type of image data in the first medical examination data.

[0084] The part recognition text feature extraction process includes the following:

[0085] Non-standardized text cleaning: A noise filtering model built using regular expressions + Bi-LSTM;

[0086] Part feature extraction: A domain-specific BERT model (MedBERT) built on the medical knowledge graph;

[0087] Contextual reasoning: Use the Transformer architecture to establish a mapping relationship between part descriptions and standard terminology.

[0088] Different parts of the image are identified using different methods to extract the following images:

[0089] Anatomical structure positioning: Improved U-Net network achieves three-dimensional spatial positioning (for CT / MRI);

[0090] Multi-scale feature fusion: Using the Inception-ResNet hybrid architecture to process images of different resolutions; Projection recognition subsystem: Integrating the CheXNet model to process X-ray two-dimensional projection recognition.

[0091] Step S3: Based on the first recognition parameter or the standard recognition parameter, the part recognition text feature and the part recognition image feature are fused and analyzed to obtain the similarity between the part recognition text feature and the part recognition image feature, and then obtain the first confidence between the part recognition text feature and the part recognition image feature.

[0092] In this specific embodiment, step S3 includes:

[0093] According to the first recognition parameter or the standard recognition parameter, it is realized by the cross attention mechanism;

[0094] A confidence weighted model is constructed based on the DS evidence theory, and the first confidence between the part recognition text features and the part recognition image features is obtained through the confidence weighted model.

[0095] It should be noted that feature fusion can further integrate feature information from different modalities to generate a more expressive and robust feature representation technology.

[0096] Step S4: In response to the first confidence being greater than the standard confidence, a fusion feature is obtained, and the fusion feature is input into the RAG industry model analysis system, so that the RAG industry model analysis system outputs data-standardized part identification data corresponding to the first medical examination data.

[0097] In this specific embodiment, the RAG industry model analysis system includes:

[0098] Standard terminology database: integrating domestic and international data standards and specifications;

[0099] Inspection item comparison table: Build a comparison table containing more than 100 medical institution inspection items and standard parts;
