1. A system comprising:
a machine readable storage medium storing instructions; and
a processor to execute the instructions to:
receive radial k-space magnetic resonance imaging (MRI) data of a patient;
determine a series of dipole sources via direct dipole decomposition of the radial k-space MRI data by determining a secular dipole basis and extracting the series of dipole sources from the radial k-space MRI data based on the secular dipole basis; and
identify an activation within the patient based on the series of dipole sources.
