Abstract :
In this study, some indexes of blood flow, which is frequently used in clinics, is measured. Sonograms was obtained by software algorithms with Doppler shift frequency, saved from patients. After that, sonogram systolic and diastolic peak amplitudes was calculated from the envelope which was obtained from the B-spline interpolation to sonogram envelope. With the help of these amplitudes, Pourcelot´s resistance index and the ratio of systolic peak amplitudes to diastolic peak amplitudes was calculated
