Abstract

The invention discloses a method and device for reconstructing a dynamic magnetic resonance image and a readable storage medium, and relates to the technical field of image processing. The method forreconstructing the dynamic magnetic resonance image comprises the steps of obtaining to-be-reconstructed sampling data in the dynamic magnetic resonance image; Decomposing the dynamic magnetic resonance image into a background low-rank tensor component and a changed foreground sparse tensor component according to the local change characteristic of the dynamic magnetic resonance image; Processing the sampling data through a preset low-rank model to obtain a background low-rank tensor component; Processing the sampling data through a preset sparse model to obtain a changed foreground sparse tensor component; Based on the background low-rank tensor component and the changed foreground sparse tensor component, the dynamic magnetic resonance image is reconstructed, and the data structure correlation of the dynamic magnetic resonance image data in the time dimension and the space dimension can be fully utilized.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and readable storage medium for reconstructing a dynamic magnetic resonance image. Background technique [0002] Dynamic magnetic resonance imaging technology refers to an imaging technology that observes an observation target for a period of time and obtains multiple frames of images. At present, due to the constraints of nuclear release time and peripheral nerve stimulation in the data acquisition process of dynamic magnetic resonance imaging technology, it takes a long time to acquire data. Therefore, it takes a long time to image a certain observation target using dynamic magnetic resonance imaging technology. Contents of the invention [0003] The present application aims to provide a method, device and readable storage medium for reconstructing a dynamic magnetic resonance image, so as to reconstruct a dynamic magnetic resonance image th...
