Abstract

The embodiment of the invention discloses a medical image annotation method and device, equipment and a medium. The method comprises the steps of obtaining a to-be-annotated auxiliary image, inputtingthe to-be-annotated auxiliary image to a pre-trained target auxiliary image annotation model, obtaining an auxiliary annotation result output by the target auxiliary image annotation model; obtaininga to-be-annotated target image corresponding to the to-be-annotated auxiliary image, wherein the imaging mode of the to-be-annotated auxiliary image is different from the imaging mode of the to-be-annotated target image; and annotating the to-be-annotated target image based on the auxiliary annotation result to obtain a target annotation result of the to-be-annotated target image. According to the medical image annotation method provided by the embodiment of the invention, the to-be-annotated target image is annotated according to the auxiliary annotation structure of the to-be-annotated auxiliary image, so that the annotation accuracy of the target image is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of data processing, and in particular to a medical image labeling method, device, equipment and medium. Background technique [0002] With the development of artificial intelligence technology, medical workers can make auxiliary diagnosis based on artificial intelligence model and improve the accuracy of clinical diagnosis. [0003] A large amount of data and data labeling are required for auxiliary diagnosis based on artificial intelligence models. Data plays a crucial role in model training of artificial intelligence. High-quality data can improve the prediction accuracy of the model. When the quality of data labeling is low, the model will be difficult to learn. In the existing data labeling methods, the purpose of labeling lesions is achieved through two labeling methods: computer tomography (Computed Tomography, CT) data labeling and direct digital radiography (Direct Digit Radiography,...
