Abstract:
An imaging system includes a sensor configured to receive imaging data, where the imaging data comprises k-space data from a magnetic resonance imaging (MRI) scan of a patient. The imaging system also includes a processor operatively coupled to the sensor and configured to identify a degree of interaction between measured points of the k-space data located at a radius from a center of k-space. The processor is also configured to determine, based at least in part on the degree of interaction between the measured points, density weights for a density compensation filter. The processor is also configured to apply the density compensation filter to the k-space data to generate filtered k-space data. The processor is further configured to generate an MRI image of the patient based at least in part on the filtered k-space data.
