Method and apparatus for reconstruction of magnetic resonance imaging

摘要

A method and an apparatus for reconstruction of magnetic resonance imaging are provided. The method includes collecting data in each initial channel and filling the data in an initial K-space, the data including data in a calibration data area and data in an undersampled area; constructing a target virtual space, and mapping initial K-space data to the target virtual space; constructing, in the target virtual space, a target optimized virtual space by retaining channel data having a high signal-to-noise ratio; filling out the undersampled area in the target optimized virtual space, and acquiring complete data in the target optimized virtual space; converting the complete data in the target optimized virtual space to an image domain to obtain an image. The method advantageously increases the signal-to-noise ratio of the channel data and significantly improves the image quality.

1. A method for reconstruction of magnetic resonance imaging comprising the steps of:
collecting data in each initial channel and filling said data in an initial K-space, said data including data in a calibration data area and data in an undersampled area; constructing a target virtual space Sp, and mapping initial K-space data to said target virtual space Sp; constructing, in said target virtual space Sp, a target optimized virtual space Sp1 by retaining channel data having a high signal-to-noise ratio; filling out said undersampled area in said target optimized virtual space Sp1 and acquiring complete data in said target optimized virtual space Sp1; converting said complete data in the target optimized virtual space Sp1 to an image domain to obtain an image.
