We present a novel numerical algorithm developed to reconstuct pulsatile
blood
ow from ECG-gated CT angiography data. A block-based optimiza-
tion method was constructed to solve the inverse problem corresponding to the
Riccati-type ordinary di?erential equation that can be deduced from conserva-
tion principles and Hook's law. Local
ow rate for 5 patients was computed
in 10 cm long aorta segments that are located 1 cm below the heart. The
shapes of the local
ow rate curves seem to be very realistic. Our approach
is suitable for estimating characteristics of pulsatile blood
ow in aorta based
on ECG gated CT scan thereby contributing to more accurate description of
several cardiovascular lesions.
