Abstract

The invention relates to an image reconstruction method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining ASL control data and ASL mark data of a plurality of segments of a target region in a K space, carrying out the independent reconstruction of the ASL control data of each segment, and obtaining a first complete image corresponding to the ASL control data of each segment; independently reconstructing the ASL mark data of each segment to obtain a second complete image corresponding to the ASL mark data of each segment; combining the first complete images corresponding to the segments to obtain a control image after reconstruction of the target area; and combining the second complete images corresponding to the segments to obtain a marked image after reconstruction of the target area. According to the method, the image without artifacts can be reconstructed, so that the accuracy of the reconstructed image is greatly improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image reconstruction method, device, computer equipment and storage medium. Background technique [0002] Arterial spin labeling (ASL) imaging technology usually requires the use of high-speed three-dimensional data acquisition sequences to achieve perfusion imaging covering the whole brain. [0003] For example, 3D GRASE (Gradient Recalled And Spin Echo, spin echo FSE and gradient echo EPI combination sequence) sequence is one of the most commonly used three-dimensional data acquisition sequences for ASL. Taking the 3D GRASE sequence as an example, usually a complete 3D K-space data needs to be divided into several GRASE echo chains for segmental acquisition, and each echo chain collects a part of the K-space data in the phase encoding (PE) direction, and then The K-space data collected in each segment are spliced ​​along the PE direction to form a complet...
