Title: David Tucker and Phase-Contrast MRI Innovation.

Introduction

David Tucker is an inventor associated with Columbus, Ohio, and The Ohio State University. His patent work addresses velocity estimation in phase-contrast magnetic resonance imaging (MRI).

Latest Patents

Tucker is credited with 1 patent: “Venc Design and Velocity Estimation for Phase Contrast MRI.” The invention describes systems and methods for implementing Phase Recovery from Multiple Wrapped Measurements (PRoM), a fast, approximate maximum-likelihood estimator for velocity from multi-coil data, including data affected by amplitude attenuation due to dephasing.

The method uses pairwise phase differences and their inherent correlations to reduce estimation error. It can recover a broad range of unambiguous velocities, potentially exceeding four times the highest velocity-encoding (VENC) value. The patent also describes deriving probabilities of unwrapping errors and a posterior probability distribution for velocity estimates, supporting optimized design of phase-encoded acquisitions.
