The embodiment of the invention provides an image processing method, a device, CT equipment and a CT system. According to the embodiment of the invention, a to-be-processed target original reconstructed image is obtained, wherein the target original reconstructed image is a CT image containing cone angle artifacts; all pixel values of an air region in the target original reconstructed image are set as a first value, and all pixel values of a soft tissue region in the original reconstructed image are set as a second value to obtain a target base image; a target error image corresponding to thecone angle artifact in the target original reconstructed image is determined according to a target base image; the target error image is subtracted from the target original reconstructed image to obtain a target image; and an error image capable of representing the cone angle artifact more accurately is acquired based on the image domain, and the error is small, so that the cone angle artifact inthe target original reconstructed image can be removed more accurately, and the image quality is improved.
Description
technical field [0001] The invention relates to the technical field of medical image processing, in particular to an image processing method, device, CT equipment and CT system. Background technique [0002] CT (Computed Tomography, computerized tomography) imaging is a safe and accurate non-invasive imaging technology, which is widely used in the medical field. However, there are more cone angle artifacts in some scan types of CT reconstruction images, such as circular cone-beam CT scans, spiral cone-beam CT scans, and so on. In these CT scans, the larger the cone angle, the worse the cone angle artifact. The existence of cone angle artifacts seriously affects the image quality and brings great interference to doctors using CT images for auxiliary diagnosis. Contents of the invention [0003] In order to overcome the problems existing in related technologies, the present invention provides an image processing method, device, CT equipment and CT system, which can reduce ...
