Abstract

A flow-phantom study utilizing constant and pulsatile flow was performed to determine the manufacturer and machine setting based variation of the maximum velocity envelope (MVE), and model parameters (c,k) obtained from model-based image processing (MBIP). Both numerical and flow-phantom experiments indicate that variations of c and k are a function of the magnitude of c and k and exhibit directional dependence. A processing method which minimizes the effects was derived and tested. The results show that the variations in the size of the parameters due to machine type and setting fall within c-k space domains of constant mean-square error. The variation due to machine type and setting is less than variation due to physiologic or inter-group variability.
