Abstract

The invention discloses an image reconstruction method and device, a storage medium and electronic equipment. The method comprises the following steps: acquiring an original scanning image; wherein the original scanning image is a three-dimensional image; performing first high-frequency component removal on a first shape surface of the original scanning image to obtain a processed first image; wherein the first plane is a sagittal plane or a coronal plane; performing cross section high-frequency component extraction on the original scanning image to obtain a target high-frequency component; wherein the target high-frequency component at least comprises a first high-frequency component corresponding to the first shape surface; and compensating the first image based on the target high-frequency component to obtain a first target image. The high-frequency components of the sagittal plane or the coronal plane are removed from the original scanning image to obtain the processed image, and then the target high-frequency information extracted from the original scanning image is compensated to the processed image, so that the image without the windmill artifacts can be obtained, and the reconstructed image is clearer.

Description

technical field [0001] The present application relates to the technical field of tomography, and in particular to an image reconstruction method, device, storage medium and electronic equipment. Background technique [0002] With the rapid development of CT technology, multi-slice CT is becoming more and more common. Windmill artifact is a common artifact in multi-slice CT. The artifact is manifested by alternating white and black bars, and the number of white and black bars is equal to the number of detector layers. At present, there are two main methods for removing windmill artifacts. One is mainly to increase the axial sampling rate from the hardware to remove windmill artifacts, such as Z flying focus technology. The disadvantage of this method is that it requires high hardware support equipment. ; The other mainly starts from the software and uses algorithms to remove windmill artifacts. The current main algorithm is to post-process the image to remove it, and the de...
