SYSTEM AND METHOD FOR CONTROLLING CONCOMITANT GRADIENT PHASE ERRORS IN CHEMICAL-SHIFT ENCODED IMAGING

View U.S. Patent No. 11,686,798 in PDF format.

WARF: P210441US01

Inventors: Nathan Roberts

The Invention

A UW-Madison researcher has devised a novel complex fitting method that addresses concomitant gradient (CG) phase errors in chemical shift-encoded (CSE) MRI estimation of proton density fat fraction (PDFF) and R2* estimation through joint estimation of pass-specific phase terms.

Applications

Proton Density Fat Fraction estimation with 3T MRI
