These parameters are determined only by the sound source:

With a 5 MHz transducer the sound wave is traveling through a medium at a speed of 1500 m/s.  The depth is decreased from 8 cm to 4 cm.  What happens to the frequency?

Attenuation coefficient increases as:

Which of the following contributes to improve the axial resolution in a B-mode image?

Huygen’s principle relates to:

A reduction of intensity to one half its original value is _________ dB.

The intensity of a beam is 50 mW/cm2.It is increased by 3 dB. What is the new intensity?

What are the units for azimuthal resolution?

Imaging transducers are:

In a transverse wave, particles move in a direction perpendicular to the direction that the wave propagates.
