Reliable estimates of aortic distensibility and pulse wave velocity and their variation along the axis of the vessel can be derived by registration of time series images using a regularisation term based on the one-dimensional wave equation. Validation is from numerical phantom data, and results are presented from clinical images for six cases of mild aortic coarctation.
