HARP is a commonly used technique for analyzing tagged
images. Nevertheless, HARP tracking of the material
points fails near the myocardial boundaries. Band-Pass
Optical Flow (BPOF) is a motion analysis technique that,
similar to HARP, is based on k-space analysis, but
enforces optical flow constraints, which could provide a
remedy to the HARP limitation. The purpose of this work
is to use BPOF for calculating strain from tagged
images, and compare the results to HARP at different
myocardial regions based on numerical phantom and
in-vivo images. The results show that BPOF is superior
to HARP in tracking boundary taglines.
