A nonlinear, self-calibrated phase-contrast (SCPC)
correction method is proposed, which provides an
improved fit of the static nonlinear phase in
quantitative cardiac phase-contrast imaging. In
addition, the method improves on the static tissue
detection, takes into account the quiescent cardiac
phase, and has an over-fitting prevention step. Normal
subjects were imaged at 1.5T and 3T, with the resulting
phase validated using a static phantom. The Qp/Qs ratios
of seven patients without cardiac shunt were recorded,
demonstrating an improved Qp/Qs ratio with the method.
