Magnetic resonance imaging high-speed reconstruction method and magnetic resonance imaging equipment

摘要

PROBLEM TO BE SOLVED: To provide a magnetic resonance image high-speed reconstruction method and a magnetic resonance imaging apparatus capable of restoring a high-resolution image while shortening both the imaging time and the reconstruction time. A high-speed magnetic resonance imaging reconstruction method uses a multi-resolution convolutional neural network to restore a high-resolution image from a first k-space data based on an original signal observed by magnetic resonance. Includes S3). In the multi-resolution convolutional neural network, second k-space data having different sizes is generated from the first k-space data, and images obtained from each of the first k-space data and the second k-space data are super-resolutiond. A high-resolution image is restored by super-resolution using an image convolutional neural network and superimposing the super-resolution images to match the size. [Selection diagram] FIG. 10
