Answer:
fR = f(c + v)/c
Explanation:
The speed of a wave is its frequency x wavelenght. Therefore,
Frequency is speed of wave over the wavelength.
Since the source (ultrasound machine) is stationary, and the receiver red blood cell is moving towards it. The wavelenght of the wave sent out towards the observer is c/f
The speed of the reflected sound wave is (c + v), so that the reflected frequency fR is given by
fR = f(c + v)/c

That's the familiar description of a comet.
If I were the amateur astronomer who discovered the new comet, then
according to the tradition of the astronomical community, I would have
the privilege of naming it. I would call it Comet AL2006/2016.
