Method and device for generating CT image containing motion artifacts and storage medium

Abstract

The invention provides a method and device for generating a CT image containing motion artifacts and a storage medium. The method comprises the following steps: receiving a CT image without motion artifacts; processing the received CT image to obtain projection data of the CT image; determining motion artifact parameters, and adjusting the projection data according to the motion artifact parameters; and performing CT image reconstruction on the adjusted projection data to obtain a CT image containing motion artifacts. According to the CT image containing the motion artifact generated by the method, the CT reconstruction theory and the motion artifact generation situation are considered, and the CT image is basically consistent with the situation that the motion artifact is generated in thehead CT scanning process of a patient. Although the data is simulation data, the data is very close to the real situation, and a large number of training data sets close to the real situation are provided for development of a novel algorithm based on artificial intelligence and deep learning.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a method, device and storage medium for generating CT images containing motion artifacts. Background technique [0002] X-ray computed tomography (Computed Tomography, CT) technology has been widely used in medical diagnosis, and is one of the indispensable medical imaging technologies for clinical diagnosis today. CT imaging theory assumes that the patient remains still during the imaging process, but CT imaging takes a certain amount of time, and the patient may move voluntarily or involuntarily, resulting in motion artifacts in the reconstructed CT image and affecting the quality of CT imaging. Therefore, it is of great significance to study the correction methods of motion artifacts. [0003] In recent years, some progress has been made in the recognition and correction of motion artifacts in CT images based on artificial intelligence and deep learning methods. How...
