Abstract

The invention discloses an intelligent dose planning method for brachytherapy intraparticle radiotherapy surgery, which includes the steps of: training the artificial neural network model, training the corresponding relationship between voxel points and dose values ​​in the target target area, and obtaining a prediction model; when a new case is input, Using the prediction results obtained by the prediction model and the contour and geometric parameters of the target area of ​​the new case, the twin neural network model is used to search for matching similar cases in the prior case database; the particle distribution state of the matched similar cases is used as the dose of the new case The initial state of the plan, as the initial solution in the simulated annealing algorithm, is optimized and evaluated by the DVH evaluation method to obtain the current case operation plan. The present invention uses prior cases as a database, uses artificial intelligence technology to match and optimize new cases, and finally can accurately and quickly formulate an optimal preoperative plan that meets clinical requirements.

Description

technical field [0001] The invention relates to the technical field of medical radiation intelligence, in particular to an intelligent dose planning method for brachytherapy intraparticle radiotherapy. Background technique [0002] In the process of cancer treatment, radiotherapy can be used alone as a method of treating cancer, or it can be combined with other treatment methods (such as chemotherapy and surgery) for adjuvant therapy, so it is used in most cancer treatment operations. Brachytherapy is a common treatment method of internal radiotherapy. Its principle is that particles containing radioactive substances are implanted near the cancer lesion for a short time or permanently, and continuously irradiate the lesion to achieve the therapeutic effect. Compared with external radiotherapy, brachytherapy has a smaller radiation exposure range, relatively higher dose, stronger local controllability, less side effects on the human body, and a lower chance of causing radiati...
