Patent ID: 7098662

Claim:
An MRI apparatus comprising: a plurality of gradient coils positioned about a bore of a magnet to impress a polarizing magnetic field and an RF transceiver system and an RF switch controlled by a pulse module to transmit RF signals to an RF coil assembly to acquire MR images; and a computer programmed to: sample an excited echo to acquire non-phase-encoded, ramp-sampled MR reference data; determine phase correction coefficients from the non-phase-encoded, ramp-sampled MR reference data, sample an excited echo to acquire phase-encoded ramp-sampled MR data; phase correct the phase-encoded, ramp-sampled MR data using phase correction coefficients from the non-phase-encoded, ramp-sampled MR data; re-sample the phase-corrected MR data; and reconstruct an image from the re-sampled MR data.
