Our current research is focused on using imaging technologies
to obtain detailed understanding of how the heart works as
an efficient mechanical pump, and how blood flow in the myocardium
is organized at the capillary level. We develop non-invasive
MRI imaging techniques and other more invasive methods in
this pursuit.

“Three-dimensional motion
tracking of the left ventricle of the human heart during
contraction. The downward movement of the base of the
heart toward the apex and the twisting motion of the apex
are clearly visible.” Click here for a higher resolution of this

We use DENSE, an MRI technique, to track tissue motion
within the myocardium at 1 mm resolution and 100 frames/sec
in this transverse slice.
