This work looks at the feasibility of performing sparse
sampling in high resolution phase contrast imaging using
a CS-SENSE reconstruction algorithm. Images were
simulated at 25, 18, and 14% sparse acquisition and
compared against a clinical acquired dataset through
region of interest analysis. Undersampled data showed
slight underestimation of quantitative values while
still maintaining an accurate flow curve behavior. The
intrinsic nature of undersampling most likely leads to
quantitative discrepancy. CS-SENSE is shown to be
feasible and promising achieving accurate quantitative
data.
