Image search method and device based on artificial intelligence, equipment and medium

Abstract

The invention discloses an image search method and device based on artificial intelligence, equipment and a medium. The image search method based on artificial intelligence comprises the steps: obtaining an image search request which comprises a target user identifier, an original CT image corresponding to the target user identifier and an original endangered organ sketching image; inputting the original CT image and the original endangered organ sketch image into a dose analysis model to generate an original dose distribution map corresponding to the target user identifier; performing registration processing on the original dose distribution map to obtain a standard dose distribution map; inputting the standard dose distribution map into an image search model, and obtaining a target feature vector corresponding to the target user identifier; and querying a radiotherapy plan database based on the target feature vector, and obtaining a target dose distribution map matched with the target feature vector. According to the image search method based on artificial intelligence, the acquisition efficiency and accuracy of the target dose distribution map can be improved.

Description

technical field [0001] The present invention relates to the technical field of medical image processing, in particular to an image search method, device, equipment and medium based on artificial intelligence. Background technique [0002] Tumor radiotherapy (referred to as radiotherapy) is the use of radiation such as α, β, γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray radiotherapy machines or accelerators to treat malignant tumors. A method of local radiation therapy. During radiotherapy, a radiotherapy plan needs to be designed based on the dose distribution map, so that radiotherapy can be performed based on the radiotherapy plan. In the design of radiotherapy plan, the dose distribution map is usually manually operated by physicians and physicists. Due to the high similarity between the target organ and surrounding tissues, the prescription dose levels are diverse, and there are many s...
