Abstract
A system includes a machine readable storage medium storing instructions and a processor to execute the instructions. The processor executes the instructions to receive radial k-space magnetic resonance imaging (MRI) data of a patient and determine a series of dipole sources via direct dipole decomposition of the radial k-space MRI data. The processor executes the instructions to identify an activation within the patient based on the series of dipole sources.
Claims20
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.
