What is the Doppler shift frequency in soft tissue, in which the speed of sound is 1540 m/s, if the transmitted frequency is 2 MHz, and the velocity of a reflector is 20 cm/s?

Question

Quizplus · Accepted Answer

The Doppler shift frequency can be calculated using the formula: $ f_d = \frac{2 \times f_t \times v_r}{c} $, where $ f_d $ is the Doppler shift frequency, $ f_t $ is the transmitted frequency, $ v_r $ is the velocity of the reflector, and $ c $ is the speed of sound in the medium. Substituting the given values: $ f_d = \frac{2 \times 2 \times 10^6 \times 0.2}{1540} \approx 520 $ Hz.
