Assignee: NORTHWESTERN UNIVERSITY
Field: Measurement (Instruments)
Classification: CPC G  A | IPC G

Claim 0:
1. An imaging system comprising:
a sensor configured to receive imaging data, wherein the imaging data comprises k-space data from a magnetic resonance imaging (MRI) scan of a patient;
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;
determine, based at least in part on the degree of interaction between the measured points, density weights for a density compensation filter;
apply the density compensation filter to the k-space data to generate filtered k-space data;
generate an MRI image of the patient based at least in part on the filtered k-space data; and
convert the filtered k-space data from a polar coordinate system to a Cartesian coordinate system using gridding, wherein the conversion results in filtered and gridded k-space data with uniform density weights across k-space, and wherein the processor performs a Fourier transform to generate the MRI image of the patient based at least in part on the filtered and gridded k-space data.
