Popis:	Flow measurements were carried out on a phantom simulating tissue, using systematic variations of various parameters and of relevant geometric factors. The effect of imaging and flow parameters on the accuracy of the measurements is described and the conditions are defined which are necessary for obtaining a high degree of accuracy. Large errors are introduced by measurements carried out with large Doppler angles or if the delimiters used for automatic vessel measurements have not been set up accurately.
