In this study we have shown the feasibility of the combination of cardiac Short Axis (S.A) and Long Axis (L.A) images that provides a more comprehensive data from DENSE MRI in 20 to 40% shorter time. Estimating the magnitude of the displacement field for a region on one of the S.A layers by its adjacent S.A and L.A neighbors resulted in 29% relative root mean squared (rms) error. It is almost equal to the 24% relative rms difference of the same parameter calculated based on S.A and L.A acquisitions for the points on the intersection of those layers.
