A doppler blood flow meter emits ultrasound at a frequency of 5.0 MHz. The speed of sound in human tissue is 1540 m/s. The blood is moving at 0.15 m/s. A. What is the frequency shift do to the motion of the blood (Ch. 15)? B. What is the frequency of the waves reflected off the blood? C. What is the beat frequency of the interference between the emitted and reflected waves?
A Doppler ultrasound is used to measure blood flow speeds, for instance, in a patient's artery. Assume the probe emits ultrasound waves at a frequency of 5 x 1O^6 Hz and the speed of sound in human tissue is 1540 m/s. (a) Why is the Doppler effect the basis of the mechanism of an ultrasound machine? (b) What is the frequency, f" received by the probe if the beat frequency, that is, the frequency shift following reflection, is 400 Hz...
Review I Constants Part A An echocardiogram uses 4.4 MHz ultrasound to measure blood flow in the aorta. The blood is moving away from the probe at 1.7 m/s What is the frequency shift of the reflected ultrasound? Use values given in the table if necessary. Enter a positive value if the received frequency is higher than the emitted frequency, and a negative value if the received frequency is lower than the emitted frequency. Express your answer to two significant...
