Problems solved by technology

[0004] During the design and implementation of radiation therapy plans, the nomenclature of radiotherapy structures is diversified. The nomenclature of radiotherapy structures varies from disease to disease, from person to person, and from time to time. Inconsistent or inappropriate naming of radiotherapy structures may easily lead to omissions and confusion, making safety Sexual problems are more prominent and attract attention, which brings ambiguity to plan design and difficulties in later dose statistical analysis

[0095] On the basis of the first embodiment of the present invention, the training process of the standardized model includes the following steps:

[0096] a. Perform symbolic preprocessing on the second original structure names corresponding to the collected original structure sample files, so as to generate at least one sample string corresponding to each second original structure name.

[0097] In the embodiment of the present invention, the terminal device obtains nearly 1,000 radiation treatment plans of patients to be used as original structure sample files for training. After the doctor outlines all the structures and saves the structure names, they are saved in the planning system. The terminal device Automatically exported from the planning system (can be read by the software as a local file or sent to the software for reading), the radiotherapy plan includes 2D (two-dimensional) radiotherapy plan, 3DCRT (three-dimensional conformal radiotherapy) radiotherapy plan , d...

[0107] On the basis of the second embodiment of the present invention, the establishment process of the structured lexicon includes:

[0108] A. Analyzing the obtained original structure sample file to obtain substructure fields.

[0109] In the embodiment of the present invention, the terminal device obtains the radiotherapy plans of nearly 1,000 patients. After the doctor outlines all the structures and saves the structure names, it is stored in the planning system. The terminal device is automatically exported from the planning system (it can be used as a local The file is read by the software or sent to the software for reading), the terminal device parses the obtained original structure sample file to obtain the substructure field, that is, the original structure name, and the following is the reading of the local file Take an example to explain: use MATLAB software to analyze the original structure file, first, find the path under the folder of the original radiotherapy ...

[0115] On the basis of the above embodiments of the present invention, it also includes:

[0116] When the first regular expression does not match the second regular expression in the standardized model, the standardized model and the structured thesaurus are updated according to the first regular expression.

[0117]In this embodiment of the present invention, when the first regular expression fails to match the second regular expression in the standardized model, the terminal device updates the The second regular expression stored in the standardized model and the structure lexicon, establish the association relationship between the first regular expression and the structure lexicon, so that the same first regular expression can be regenerated next time , it can match the corresponding standardized naming in the structured thesaurus, realizing the sustainable use of the standardized model and the structured thesaurus.

Abstract

The present invention discloses a radiation structure naming standardization method, apparatus and device and a computer readable storage medium. The method comprises the steps of: receiving an inputoriginal structure file, and obtaining a first original structure name of the original structure file; performing signifying preprocessing of the first original structure name to generate at least onecharacter string; according to the at least one character string, generating a first regular expression; according to a trained standardization model, performing expression matching for the first regular expression; according to a second regular expression in the standardization model matching with the first regular expression and a structure word bank associated with the second regular expression, converting the first original structure file to a standard structure name, wherein the structure word bank is configured to store the standardization name of each tumour radiotherapy treatment structure; and outputting the standard structure file according to the standard structure name to avoid confusion caused by inconsistent and improper names.

Description

technical field [0001] The invention relates to the field of computer medical technology, in particular to a standardized naming method, device, terminal equipment and computer-readable storage medium for radiotherapy structures. Background technique [0002] Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients need radiotherapy in the course of cancer treatment, and about 40% of cancers can be cured with radiotherapy. The role and status of radiotherapy in tumor treatment has become increasingly prominent, and it has become one of the main means of treating malignant tumors. With the help of the development of CT imaging technology and computer technology, the current radiotherapy technology has developed from two-d...
