Three-dimensional magnetic resonance image super-resolution reconstruction method, electronic equipment and storage medium

Abstract

The invention provides a three-dimensional magnetic resonance image super-resolution reconstruction method, electronic equipment and a storage medium. The three-dimensional magnetic resonance image super-resolution reconstruction method comprises the steps of determining a three-dimensional magnetic resonance image; determining a first slice sequence of the three-dimensional magnetic resonance image in the first slice direction, performing two-dimensional super-resolution reconstruction on the first slice sequence to obtain a first reconstruction sequence, and reconstructing a first three-dimensional image based on the first reconstruction sequence; and determining a second slice sequence of the first three-dimensional image in the second slice direction, performing two-dimensional super-resolution reconstruction on the second slice sequence to obtain a second reconstruction sequence, and reconstructing the high-resolution three-dimensional image based on the second reconstruction sequence. According to the method, the electronic equipment and the storage medium provided by the invention, two-dimensional super-resolution reconstruction is alternately carried out in two directions, so that the continuity of a super-resolution reconstruction result is ensured. In the process, the realization of two-dimensional super-resolution reconstruction does not need to provide and apply a high-resolution three-dimensional image, so that the acquisition difficulty and the acquisition cost of the training sample are greatly reduced, and the practicability of the method is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a three-dimensional magnetic resonance image super-resolution reconstruction method, electronic equipment and a storage medium. Background technique [0002] Three-dimensional magnetic resonance (Magnetic Resonance, MR) imaging has the advantages of no radiation, multiple parameters, and good soft tissue contrast, and has been widely used in clinical practice. [0003] At present, three-dimensional magnetic resonance images often need to be obtained through a series of two-dimensional images, and the scanning time and cost are often saved by increasing the scanning distance during the image scanning process. However, increasing the scanning distance will lead to a decrease in the interlayer resolution of 3D image data, which will affect the evaluation reliability of clinical diagnosis. [0004] To solve this problem, the interlayer resolution is usually improved by 3D d...
