BRIEF DESCRIPTION OF DRAWINGS
[0045] Figure 1 is a system structure block diagram of the application.
[0046] The following specific embodiments will further illustrate the application in conjunction with the above drawings. DETAILED DESCRIPTION
[0047] Please refer to Figure 1 In a preferred embodiment of the application, an early screening system of pulmonary interstitial fibrosis based on big data analysis includes a data acquisition module, a model verification module, a data preprocessing module, a data storage module, a data analysis module and a result output module. Specifically,
[0048] The data collection module is configured to collect data related to pulmonary fibrosis, specifically medical image data, and to extract features from the medical image data to obtain feature data, which is then sent to the model verification module. The medical image data includes chest X-ray images and CT images of patients. During feature extraction, each image data is extracted and compared with the corresponding image in the normal state to obtain an abnormal feature region map for each image data. The abnormal feature region map is the feature data.
[0049] For example, for a patient's chest X-ray image, features are extracted from the chest X-ray image and compared with the chest X-ray image in the normal state to obtain chest abnormal feature regions. Similarly, for a patient's CT image, features are extracted from the CT image and compared with the CT image in the normal state to obtain CT abnormal feature regions. The same processing method is used for other images. It should be noted that during feature extraction, there may be more than one abnormal feature region map for each type of image data, and multiple abnormal feature regions need to be processed.
[0050] The model verification module is connected to the data collection module through data transmission technology and is configured to associate the feature data of the medical image data extracted by the data collection module to obtain a plurality of association images. Each association image is input into the constructed pulmonary fibrosis early screening model to obtain an evaluation value of the pulmonary fibrosis feature coefficient. The evaluation value is paired with the true value of the training set in the model to obtain true positives, false positives, and false negatives. The error scores of the true positives, false positives, and false negatives are calculated, and the multiple association images are processed according to the calculated error scores. The processing methods include image elimination and image revalidation. The processed association images are sent to the data preprocessing module.
[0051] In the present application, the pulmonary fibrosis early screening model construction method is as follows:
[0052] S1, obtain historical chest X-ray images and historical CT images of a plurality of pulmonary fibrosis patients, and extract features from the historical chest X-ray images and historical CT images to obtain X-ray abnormal feature maps and CT abnormal feature maps. The X-ray abnormal feature map and the CT abnormal feature map of the same patient are integrated into an association image as a training sample.
[0053] S2, construct a pulmonary fibrosis early screening model based on a deep learning network, and divide the generated training sample into a training set and a test set according to a ratio of 8:2.
[0054] S3, download the weight file and load it to the BP neural network, which is used to initialize the migration network parameters, and determine the number of hidden layer nodes of the BP neural network model according to the number of associated images in the training set;
[0055] S4, modify the last fully connected layer of the BP neural network, keep the input unchanged, set the output as the pulmonary fibrosis feature coefficient, initialize the weight of the last layer, use gradient descent algorithm for learning, and adopt fixed step attenuation to optimize the training parameters, retrain the whole network, and obtain the pulmonary fibrosis early screening model;
[0056] S5, during the training process, a small batch of associated images are randomly and repeatedly extracted from the training set, and all the associated images in the training set are extracted as a training cycle, and the training is completed after a certain cycle is iterated, and then the test set is used to evaluate the effect of the pulmonary fibrosis early screening model.
[0057] In the model verification module, the error score is calculated by the following calculation method:
[0058]
[0059] In the formula, the error rate represents the proportion of all error classification samples in the total sample number, which is used to measure the overall error rate of the classifier;
[0060] TP is the true positive, which represents the number of samples that are actually positive and are correctly classified as positive by the classifier;
[0061] FP is the false positive, which represents the number of samples that are actually negative but are incorrectly classified as positive by the classifier;
[0062] FN is the false negative, which represents the number of samples that are actually positive but are incorrectly classified as negative by the classifier;
[0063] TN is the true negative, which represents the number of samples that are actually negative and are correctly classified as negative by the classifier.
[0064] The above TP, FP, FN and TN constitute a confusion matrix, that is, in the classification problem, the confusion matrix is used to calculate the true positive, false positive, false negative and other indicators, and then different error scores are calculated.
[0065] In the present application, the construction of the early screening model of pulmonary interstitial fibrosis is based on historical big data, and since the diagnosis result in the historical big data is a definite result, the data of the patient to be tested is applied to the early screening model of pulmonary interstitial fibrosis, and based on the big data analysis of the historical data, the pulmonary interstitial fibrosis characteristic coefficient obtained by analysis will be a relatively accurate judgment result, therefore, the reasoning result obtained from the model judges the correctness of the characteristic data extracted by the data acquisition module, which can effectively process the defective characteristic data and retain the accurate characteristic data, so that through subsequent data analysis and processing of these accurate characteristic data, the early characteristics of pulmonary interstitial fibrosis can be accurately identified, thereby assisting doctors in diagnosing the early stage of pulmonary interstitial fibrosis, greatly improving the accuracy of the diagnosis and reducing the missed diagnosis and misdiagnosis.
[0066] The data preprocessing module is connected with the model verification module through data transmission technology, and is used for disassociating the processed associated images, calculating characteristic values based on the disassociated features, cleaning, denoising and standardizing the calculated characteristic values to obtain standardized characteristic values. When calculating the characteristic values, the area of the abnormal feature region in each feature is calculated, and the obtained area data is the characteristic value.
[0067] In the present application, the associated image is image information obtained by associating various medical image data, each associated image is composed of multiple feature data, and each feature data is extracted from one kind of medical image data. In the data preprocessing module, each feature data needs to be processed. For example, for the chest X-ray image of a patient, the chest abnormal feature region is obtained by feature extraction based on the chest X-ray image, and the area of the chest abnormal feature region is calculated to obtain a characteristic value one. Similarly, for the CT image of a patient, the CT abnormal feature region is obtained by feature extraction based on the CT image, and the area of the CT abnormal feature region is calculated to obtain a characteristic value two. Since the number of feature data corresponding to each kind of medical image data is not one, the number of characteristic value one and characteristic value two obtained is not one.
[0068] In the present application, after the characteristic values are calculated, the characteristic values need to be preprocessed to obtain standardized characteristic values, wherein the following calculation formula is used to standardize the received data:
[0069]
[0070] In the formula, y is the characteristic value, y i is the standardized characteristic value, μ is the mean of the feature, and σ is the standard deviation of the feature.
[0071] The data storage module is connected with the data preprocessing module through data transmission technology and is used for storing the preprocessed data. In the embodiment, the data storage module adopts a distributed storage architecture and stores different types of data on different nodes in the blockchain.
[0072] The data analysis module is connected with the data storage module through data transmission technology and is used for analyzing and judging the preprocessed data. Specifically, the lung interstitial fibrosis characteristic coefficient L(W,b) is calculated based on an analysis calculation formula, and the lung condition of the patient is judged according to the calculation result. The analysis calculation formula is as follows:
[0073]
[0074] In the formula, W is a weight vector, b is a bias vector, m is the number of samples, y i is a standardized characteristic value, is a prediction function, and The calculation formula of L(W,b) is as follows: In the formula, T is a transpose, and X is a characteristic vector of the standardized characteristic value.
[0075] In the data analysis module, the lung interstitial fibrosis characteristic coefficient needs to be calculated for all the characteristic values obtained above, and the calculated lung interstitial fibrosis characteristic coefficients are divided into multiple categories according to the sources of the characteristic values. Since there is actually a positive correlation between each category of characteristic values, when judging the lung abnormality of the patient, the lung interstitial fibrosis characteristic coefficients of each category need to be considered, rather than only considering the lung interstitial fibrosis characteristic coefficients of a single category. For example, two categories of characteristic values obtained from chest X-ray images and CT images, both of the two categories of lung interstitial fibrosis characteristic coefficients need to be referred to when judging the lung abnormality.
[0076] In the present application, the lung interstitial fibrosis characteristic coefficient is used to reflect the lung abnormality degree of the patient. The greater the value of L(W,b) is, the more serious the lung abnormality degree of the patient is, and vice versa. The smaller the value of L(W,b) is, the more slight the lung abnormality degree of the patient is.
[0077] The result output module is connected with the data analysis module through data transmission technology and is used for generating the lung interstitial fibrosis early screening result according to the lung interstitial fibrosis characteristic coefficient calculated by the data analysis module and visually displaying the generated result.
[0078] Specifically, the generation of the lung interstitial fibrosis early screening result is to evaluate the risk of lung interstitial fibrosis by comparing the lung interstitial fibrosis characteristic coefficient calculated by the data analysis module with a preset characteristic judgment range, to obtain a risk evaluation result. The risk evaluation result includes a risk category and a risk level.
[0079] Further, in the result output module, the visual display of the generated result comprises the following steps:
[0080] S1, data formatting, arranging the original result output by the data analysis module to meet the display requirements;
[0081] S2, visual processing, generating corresponding charts and reports according to the result data, wherein the charts include but are not limited to histograms, pie charts and line charts, and the reports include but are not limited to risk categories, risk levels, data sources and information explanations and diagnostic results;
[0082] S3, transmitting the formatted and visualized result to the display interface, wherein the interface includes but is not limited to the in-hospital system interface and the application program interface of the patient mobile terminal;
[0083] S4, correlation feedback, providing a user feedback entry for filling in questions about the screening result, self-symptom supplement and diagnostic supplement.
[0084] Through the system provided by the application, early and relatively accurate screening structure can be obtained, which can reduce unnecessary repeated examination of patients and alleviate the anxiety of patients waiting for the diagnosis result for a long time. At the same time, the patient can better understand the screening result and enhance the cognition of the health status, and improve the medical experience and satisfaction.
[0085] The above description is a detailed description of the preferred embodiment of the application, but the embodiment is not used to limit the scope of the patent application of the application, and any equivalent changes or modifications made under the technical spirit of the application should belong to the patent scope covered by the application.
