We demonstrate a new method to recover 4D blood
flow over the entire ventricle from partial blood velocity measurements
using multiple colour Doppler images and ventricular
wall motion estimated using BMode images. We apply
our approach to realistic simulated data to ascertain the ability of
the method to deal with incomplete data, as typically happens in
clinical practice. Experiments using synthetic data show that the
use of wall motion improves velocity reconstruction, shows more
accurate flow patterns and improves mean accuracy particularly
when coverage of the ventricle is poor. The method was applied
to patient data from 6 congenital cases, producing results consistent
with the simulations. The use of wall motion produced more
plausible flow patterns and reduced the reconstruction error in all
patients.
