Question #5

Estimate the magnitude of the Doppler shift for a situation where the velocity of blood is 1 m/s (as say in the LV outflow tract), using a 3MHz transducer, and assuming you are directly lined up with the flow of blood. Assume the velocity of ultrasound in the medium is 1500m/s.

A. 1 KHz
B. 2 MHz
C. 2 KHz
D. 4 MHz
E. 4 KHz
