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 to generate at least one sample character string corresponding to each second original structure name.

[0097] In the embodiment of the present invention, the terminal device acquires radiation treatment plans of nearly 1,000 patients, and uses them 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 as a local file by this software or sent to this software for reading), the radiotherapy plan includes 2D (two-dimensional) radiotherapy plan, 3DCRT (three-dimensional conformal radiotherapy) radiotherapy...

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

[0108] A. Parse the obtained original structure sample file to obtain the substructure field.

[0109] In the embodiment of the present invention, the terminal device obtains radiation treatment plans of nearly 1,000 patients. After the doctor outlines all the structures and saves the structure names, they are saved in the planning system, and the terminal device is automatically derived from the planning system (which 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, the following is the reading of the local file Take an example to illustrate: use MATLAB software to parse the original structure file, first, find the path under the folder of the original radi...

[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 normalization model, the normalization model and the structure 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 and the structural thesaurus stored in the standardized model, establish the association relationship between the first regular expression and the structural thesaurus, so that the same first regular expression is regenerated next time At the time, the corresponding standardized names in the structure thesaurus can be matched, so as to realize the sustainable use of the standardized model and the structure thesaurus.

Abstract

The invention discloses a radiotherapy structure standardized naming method, device, terminal equipment and computer-readable storage medium. The method includes: receiving an input original structure file, and obtaining the first original structure name of the original structure file; Perform symbolic preprocessing on an original structure name to generate at least one character string; generate a first regular expression according to the at least one character string; perform expression matching on the first regular expression according to the trained standardized model; The second regular expression in the standardized model matched by the first regular expression, and the structure lexicon associated with the second regular expression, convert the first original structure name into a standard structure name; the structure word The library is used to store the standardized naming of each tumor radiotherapy structure; the standard structure file is output according to the standard structure naming, so as to avoid confusion caused by inconsistency or inappropriate naming.

Description

technical field [0001] The present invention relates to the technical field of computer medical treatment, and in particular, to a standardized naming method, device, terminal equipment and computer-readable storage medium for radiotherapy structures. Background technique [0002] Tumor radiation therapy is a local treatment method that uses radiation to treat tumors. Radiation includes alpha, beta, and gamma rays produced by radioisotopes and x-rays, electron rays, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients require radiation therapy during the treatment of cancer, and about 40% of cancers can be cured with radiation therapy. 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 t...
