Radiation parameter determination method and device, electronic equipment and storage medium

Abstract

The invention relates to a radiation parameter determination method and device, electronic equipment and a storage medium. The method comprises the steps of performing segmentation processing on a to-be-processed image through a segmentation network to obtain a first contour of a target area and a second contour of a protection area; inputting the to-be-processed image, the first contour, the second contour and a preset radiation dose into a dose array network to obtain a dose array; inputting the dose array, the first contour and the second contour into a radiation parameter network to obtaininitial radiation parameters; and determining a target radiation parameter according to the initial radiation parameter and a preset radiation dose. According to the radiation parameter determinationmethod provided by the embodiment of the invention, a target area and a protection area in the image are automatically segmented through the segmentation network, and errors of manual intervention are reduced. The initial radiation parameters of the medical instrument are determined through the dose array network and the radiation parameter network, so that the target radiation parameters are determined, the process of determining the radiation parameters can be automatically realized, and the working efficiency and the accuracy of the scheme are improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a radiation parameter determination method and device, electronic equipment and storage media. Background technique [0002] Radiation therapy uses high-energy radiation from outside or inside the body to target cancer cells. [0003] Determining the radiation parameters of medical instruments during radiation therapy requires the use of medical 3D images of the patient. This image is first used to identify and delineate the cancerous area and surrounding organs at risk of radiation damage. Next, doses are specified for cancerous regions, and constraints are specified for organs (ie, constraints on radiation doses irradiated to organs). With potentially multiple organs and multiple tumor sites, this makes manually delineating each structure in the image time-consuming. Although automated tools are available to aid in the delineation process, the boundaries of ma...
