An echocardiogram uses 4.4 MHz ultrasound to measure blood flow in an aorta. The speed of sound in human tissue is 1540 m/s. a) If the blood is moving away from the probe at 1.3 m/s, what will be the measured shift in the frequency of the reflected ultrasound? b) How will your answer above change if the blood is moving toward the probe at the same speed? c) If the resolution of the device is 0.01 kHz, what is the slowest speed that the device will detect?

Step 1

Plugging in the given values: $$ \Delta f = \frac{2(1.3\,\text{m/s})(4.4\,\text{MHz})}{1540\,\text{m/s}} $$ Calculating the frequency shift: $$ \Delta f \approx 5.88\,\text{kHz} $$ So, the measured shift in the frequency of the reflected ultrasound when the Show more…
