Problems solved by technology

[0004] However, the process of generating radiation treatment plans by physicists manually operating the radiation treatment planning system is very time-consuming
For common cases, it takes an experienced physicist several tens of minutes to obtain a radiotherapy plan that meets the clinical requirements; for more complicated cases, it may take several hours or longer, which greatly reduces the time required for radiotherapy. Plan Generation Efficiency
And it is also difficult for physicists to determine whether the currently generated radiotherapy plan is the best plan based on their own experience, thus reducing the accuracy of plan generation

Abstract

The invention discloses radiotherapy plan generation equipment, a radiotherapy plan generation device and a storage medium. The equipment comprises one or more processors; and a memory for storing oneor more programs. When one or more programs are executed by one or more processors, the one or more processors realize the following operations: inputting image information and prescription dose information into a preset neural network model to obtain a current operation instruction; controlling a radiotherapy plan module to generate a current radiotherapy plan according to the current operationinstruction; if the current radiotherapy plan does not meet a preset cycle end condition, feeding back the current score corresponding to the current radiotherapy plan to a preset neural network modelto update the output current operation instruction, and returning to execute the operation of controlling the radiotherapy plan generation module; and if the current radiotherapy plan satisfies the preset cycle end condition, determining the current radiotherapy plan as a target radiotherapy plan so as to improve plan generation efficiency and plan generation accuracy.

Description

technical field [0001] Embodiments of the present invention relate to the field of radiation medicine, and in particular, to a radiotherapy plan generating device, device and storage medium. Background technique [0002] Radiation therapy is a common cancer treatment. Before radiotherapy, it is often necessary to formulate a better radiotherapy plan based on patient information. For example, the radiation dose distribution in the tumor area is more uniform, the dose drop around the tumor is greater, and the radiation dose to organs at risk is lower. A better radiotherapy plan can effectively treat patients with radiotherapy and improve the treatment effect. [0003] In the prior art, the doctor usually outlines the target area and organs at risk on the patient’s image and gives a prescription. The physicist manually operates the Treatment Planning System (TPS) according to the doctor’s prescription. A radiotherapy plan prescribed by a doctor and having an ideal dose volume...
