A system and method for reconstruction of magnetic resonance images acquired with partial fourier acquisition

A method for Magnetic Resonance Imaging (MRI) partial Fourier reconstruction, the method comprising:

• acquiring a first partial k-space dataset for a target area using an MRI scanner;
• creating a second partial k-space dataset for the target area based on Hermitian symmetry of the first partial k-space dataset;
• calculating a transformation matrix based on the first partial k-space dataset and the second partial k-space dataset;
• correcting the second partial k-space dataset using the transformation matrix;
• obtaining a full k-space dataset for the target area based on at least one of the corrected second partial k-space dataset, the first partial k-space dataset, and a third k-space dataset;
• and
• constructing an image for the target area based on the full k-space dataset.

A magnetic resonance imaging (MRI) system comprising:

• a magnetic field generating unit configured to apply a plurality of RF pulses with a variable flip angle to a target area in the object;
• a receiver configured to receive MR signals from the target area;
• a processing unit;
• a system memory;
• and
• machine readable instructions stored in the system memory that, when executed by the processing unit, cause the processing unit to:
• acquire a first partial k-space dataset for the target area based on the MR signals;
• create a second partial k-space dataset for the target area based on Hermitian symmetry of the first partial k-space dataset;
• calculate a transformation matrix based on the first partial k-space dataset and the second partial k-space dataset;
• correct the second partial k-space dataset using the transformation matrix;
• obtaining a full k-space dataset for the target area based on at least one of the corrected second partial k-space dataset, the first partial k-space dataset, and a third k-space dataset;
• and
• reconstruct an image for the target area based on the full k-space dataset.
