Embodiment Construction

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0026] Insufficient training samples of lesion data and labeled lesion data are the biggest obstacle to the improvement of the performance of artificial intelligence medical image analysis. Taking cerebral hemorrhage detection as an example, cerebral hemorrhage is not a frequently-occurring disease, and most of the head CT images are negative. ), there are about 1,000 cases of cerebral hemorrhage in an ordinary hospital a year, and ...

Abstract

The invention discloses an image data generation method and device, relates to the technical field of image processing, and aims to solve the problem that a data generation method in the prior art cannot provide effective training data samples for an artificial intelligence medical image analysis process. The method mainly comprises the following steps: acquiring a focus-free image; generating a predicted lesion mask according to a preset lesion contour; and inputting the focus-free image and the predicted focus mask into an image generation model to generate a predicted focus image, the imagegeneration model being generated by training a marked focus training picture. The method is mainly applied to the process of expanding the image data.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for generating image data. Background technique [0002] With the continuous improvement and improvement of deep learning algorithms, artificial intelligence medical image analysis can be used to detect and identify lesions. Artificial intelligence medical image analysis is usually based on data-driven supervised learning, which uses a posterior model based on various features, and the posterior model requires a large amount of manually labeled data for training. However, positive image data with diseases and manual annotation are not easy to obtain, which makes it difficult to improve the performance of artificial intelligence medical image analysis. Taking cerebral hemorrhage data as an example, cerebral hemorrhage is not a frequent disease, and most CT images of the head are negative. Even if a certain amount of positive data can be collected, it ...
