System and method for reconstructing k-space data

A computer implemented method for reconstructing an image from an MRI data, comprising:

• obtaining a planned radial trajectory;

• measuring a measured trajectory experienced while acquiring the MRI data;
• determining a discrepancy level between the planned radial trajectory and the measured trajectory;
• and
• selectively reconstructing the MRI data into an image using one of, the planned radial trajectory, and the measured trajectory based, at least in part, on the discrepancy level.
