| Abstract: | An automatic analysis method for Doppler ultrasound flow sonogram indeces is described in this paper. First the envelope of sonogram is recognized by digital estimation of maximum frequency. Then some sonogram indeces are automatically calculated. It is pointed out that this automatic analysis method has the reproducbility and accuracy superior to those manual methods. |
