Abstract
A magnetic resonance imaging method and system are provided. The method includes obtaining first image data using a first scan sequence, filtering the first image data to generate second image data, and estimating a radio-frequency field map based on the first and second image data. Scanned image data is then acquired using a second scan sequence and corrected using the estimated radio-frequency field map to obtain the corrected image data.
Claims17
A magnetic resonance imaging method, characterized by comprising:
- obtaining first image data by using a first scan sequence;
- filtering the first image data to obtain second image data;
- estimating a radio-frequency field map based on the first image data and the second image data;
- and
- obtaining scanned image data by using a second scan sequence, and correcting the scanned image data based on the estimated radio-frequency field map to obtain the corrected scanned image data.
