Abstract
A method for motion correction of Magnetic Resonance (MR) images is provided. The method includes acquiring a k-space dataset for an object using an MR scanner, detecting or identifying corrupted k-space data from the acquired k-space dataset, extracting the corrupted k-space data from the acquired k-space dataset, recovering the corrupted k-space data, combining uncorrupted k-space data of the acquired k-space dataset with the recovered k-space data to form a full k-space dataset, and reconstructing an image for the object based on the full k-space dataset. A magnetic resonance imaging system for correcting corrupted k-space data of an entire k-space dataset is also provided.
Claims30
A method for motion correction of Magnetic Resonance (MR) images, the method comprising:
- acquiring a k-space dataset for an object using an MR scanner;
- detecting or identifying corrupted k-space data from the acquired k-space dataset;
- extracting the corrupted k-space data from the acquired k-space dataset;
- recovering the corrupted k-space data;
- combining uncorrupted k-space data of the acquired k-space dataset with the recovered k-space data to form a full k-space dataset;
- and
- reconstructing an image for the object 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 E 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 k-space dataset for the target area based on the MR signals;
- detect or identify a corrupted k-space data from the acquired k-space dataset;
- extract the corrupted k-space data from the acquired k-space dataset;
- recover the corrupted k-space data;
- combine uncorrupted k-space data of the acquired k-space dataset with the recovered k-space data to form a full k-space dataset;
- and
- reconstruct an image for the target area based on the full k-space dataset.
