Maximizing Unambiguous Velocity Range in Phase-contrast MRI with Multipoint Encoding
Shen Zhao, Rizwan Ahmad, Lee C. Potter
In phase-contrast magnetic resonance imaging (PC-MRI), the velocity of spins at a voxel is encoded in the image phase. The strength of the velocity encoding gradient offers a trade…

MRI Recovery with A Self-calibrated Denoiser
Sizhuo Liu, Philip Schniter, Rizwan Ahmad
Plug-and-play (PnP) methods that employ application-specific denoisers have been proposed to solve inverse problems, including MRI reconstruction. However, training application-spe…

Venc Design and Velocity Estimation for Phase Contrast MRI
Shen Zhao, Rizwan Ahmad, Lee C. Potter
In phase-contrast magnetic resonance imaging (PC-MRI), spin velocity contributes to the phase measured at each voxel. Therefore, estimating velocity from potentially wrapped phase…
