Velocity profile skewing and Doppler ultrasound

Congratulations to BSL postdoc Jonathan Mynard, who has two papers coming out about the practical impact of velocity profile skewing in "straight vessels" (see our previous work here and here).  The first paper, in press with published by Ultrasound in Medicine & Biology, shows that it may not always be reasonable to infer flow rate waveform shape from maximum Doppler velocity traces, particular using a Poiseuille assumption. The second paper, accepted published by Atherosclerosis, highlights the substantial errors that can arise when trying to infer wall shear stresses from Doppler velocities under the common assumption of fully-developed flow.
