| Abstract: | A new method for quantitative measurement of blood flow velocity with Doppler ultrasound is presented. The principle of the precise velocity measurement at any angle and the method of calculation of the angle are described. The re-correction based on the practice is applied to improve the precision of the velocity measurement. Experimental results and comparisons of the method with the quasi-compensation are also given too. |
