The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.
[0029] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present invention belongs.
[0030] Embodiment 1
[0031] Reference Figure 1 , an embodiment of the present invention provides an intelligent generation and matching method for imaging standard inspection items, including the following steps:
[0032] S1: Establish a standard series library for imaging inspection items, including grading parts, equipment and types, scanning and post-processing, positioning, aliases, etc., and combine them according to industry standard specifications to generate CT, MR nuclear magnetic resonance, DR, NM nuclear medicine, and US ultrasound imaging standard item libraries;
[0033] S2: Read the original data from the standard series library of imaging inspection items and the imaging standard item library, generate and save the matching corpus, and create a common function for reading the matching corpus;
[0034] S3: Obtain the information of the inspection item to be matched input by the user, and perform training and algorithm matching of multiple machine learning models on the information of the inspection item to be matched and the data in the corpus to obtain the best matching inspection item;
[0035] S4: Obtain the query condition input by the user, extract the keywords in the query condition, and query the imaging standard item library to obtain the best standard inspection item.
[0036] According to the user's input, different results can be obtained. If the information of the inspection item to be matched is input by the user, the best matching inspection item is obtained. If the input is a query condition, the best standard inspection item is obtained. The algorithm matching method and the traditional library table query method are respectively adopted, which can meet the user's all-round needs.
[0037] Among them, the specific method of step S3 is:
[0038] S31: Obtain the name of the inspection item to be matched from the information of the inspection item to be matched, and obtain the standard item name from the corpus;
[0039] S32: Use the character-level matching model to compare the similarity between the name of the inspection item to be matched and the standard item name at the character level to obtain the character-level matching result;
[0040] S32: Use the word-level matching model to compare the similarity between the name of the inspection item to be matched and the standard item name at the word level to obtain the word-level matching result;
[0041] S33: Combine the character-level matching and word-level matching results, perform combined score weighting processing, and sort according to the scores to obtain the best matching inspection item.
[0042] Specifically, the specific method of using the character-level matching model includes the input information processing method, the inspection part matching unit method, and the inspection item name matching method to obtain the best matching inspection item:
[0043] The input information processing method maps the third-level parts to the standard names of the second-level inspection parts, maps the aliases to the standard names, formulates rules for classifying and cross-referencing problems, composite item identifiers, punctuation, English letter cases, and specific part inspection conventions for the third-level parts not covered by the standard library and alias library, combines and filters the input information, splits the input information filtered by the rules, and extracts the information required for the standard library fields from the standard library: equipment, equipment type, scanning method, post-processing, and positioning.
[0044] The inspection part matching method extracts the equipment, equipment type, scanning method, post-processing, and positioning keywords from the input information, and then uses the remaining information to match with the CT / MR / DR second-level standard inspection part corpus. Methods such as the longest common subsequence similarity calculation, edit distance similarity calculation, rule keyword weighting, and exact part name matching weighting are used for matching, and the best matching inspection part result is obtained by sorting according to the matching degree score.
[0045] The inspection item name matching method sends the inspection part, inspection method, positioning, and other information into the matching algorithm. By using the longest common subsequence similarity calculation, edit distance similarity calculation, rule keyword weighting, and exact part name matching weighting, the character-level similarity scores with each entry of the standard inspection items are calculated and sorted to obtain the rough screening recommended result set of similarity matching. Among them, the longest common subsequence similarity calculation is to extract the cumulative value feature of the length of the longest identical string contained in both matches, and measure the similarity with the length of the repeated words in the sentence. For example: A: "right humerus" vs "left humerus" counts 2; B: "right humerus", "left femur" counts 1. The similarity is measured by the maximum repeated word count, and group A with more repeated words is more similar than group B. Among them, the edit distance similarity calculation is to extract the transformation complexity of both matches, and measure the similarity features of the sentence length, sentence order, and repeated word dimension with the transformation complexity of both sides. For example: A: "right knee" vs "left knee"; B: "right knee", "left knee patella". Compared with group A, group B needs to transform 3 words to be consistent, while group A only needs to transform 1 word, which is more complex. In the case of the same longest common subsequence count, group B has a higher complexity, so group A is determined to be more similar based on the lower complexity. Among them, the rule keyword weighting means that in the similar features, the words related to the part are weighted. For example: using the longest common subsequence count, A: "right humerus" vs "left humerus" counts 2; B: "right humerus" vs "right femur" counts 2. In the case of the same count, group A has the same humerus, while group B has different parts. Then the core part word is weighted to reduce the weight of the weak related word "right". Among them, the exact part name matching weighting means that in the similar features, the exact part name is set with the highest weight. For example: "right humerus" vs "left humerus", in the case of directly matching the part name "right humerus", "right humerus" is set with the highest weight for exact matching.
[0046] The specific methods of the word-level matching model include the input information processing method, the TF-IDF matching model, and the Word2Vec matching model:
[0047] The input information processing method maps the third-level parts to the standard names of the second-level examination parts, maps the aliases to the standard names, formulates rules for the classification and cross-association problems, composite item identifiers, punctuation, English letter cases, and specific part examination conventions that are not covered by the standard library and alias library, and combines filtering and standardizes the input information;
[0048] The TF-IDF matching model reads the CT / MR / DR standard name matching corpus, performs word segmentation, creates a word list vector, inputs the sentence to be matched for word segmentation and creates a word vector representation, calculates the similarity between the input sentence vector and the traversed standard name vectors, and sorts to obtain the rough screening TF-IDF inspection item matching result set; among them, the TF-IDF term frequency-inverse document frequency model principle is to generate a term frequency word vector based on statistical thinking for vector similarity calculation;
[0049] The Word2Vec matching model reads the CT / MR / DR standard name matching corpus, performs word segmentation, trains a machine learning model to generate word vectors, calculates sentence vectors, inputs the sentence to be matched for word segmentation and creates a word vector representation, calculates the Euclidean distance and cosine distance between the input sentence and the traversed standard name sentence vectors, and sorts to obtain the rough screening word2vec inspection item matching result set; among them, the Word2Vec model is trained to generate word vectors based on the neural network machine learning idea, used to calculate the combined sentence vector, and calculates the sentence vector distance to obtain the similarity score of the two sentences;
[0050] The method of combining multiple matching result weight processing refers to reasonably adjusting the parameters to combine the character-level matching result set and the word set matching result set in principle of balancing the two directions of inspection item matching coverage and accuracy, and making a reasonable score combination weighting for the ratio of the medical imaging examination part weight to the examination method weight, so that the imaging part examination weight is greater than the examination method and positioning information weights, with the aim of improving the practical significance of the final inspection item name matching result with the part as the focus.
[0051] The above is the description of an intelligent generation and matching method for imaging standard examination items provided by the embodiments of the present invention.
[0052] An embodiment of the present invention provides a method for generating and matching medical imaging examination items, which can combine information such as examination equipment, equipment type, examination site, scanning method, post-processing, and positioning included in the examination items to generate a standard format for naming and coding examination items, as well as include functions of matching and mapping non-standard examination items to standard names using a variety of artificial intelligence matching and recommendation algorithms. The technical improvements therein include the use of artificial intelligence character-level matching algorithms such as the longest common subsequence similarity calculation, edit distance similarity calculation, rule keyword weighting, and accurate matching weighting of part names; word-level matching TF-IDF (term frequency-inverse document frequency), word2vec word vector training neural network model to calculate the sentence vector distance similarity; reasonably adjusting the parameters to combine the character-level matching result set and the word set matching result set based on the principle of balancing the coverage and accuracy of examination item matching, and making reasonable score combination weighting for the ratio of the weight of medical imaging examination sites and the weight of examination methods. It overcomes the problem that the query results of standard examination items with different orders, different combinations, different weights, and different combinations of keywords with different meanings cannot be recognized by simple fuzzy queries. The data involved covers professional terms in the field of medical imaging examinations; it formulates industry specifications for the names of imaging examination items.
