A sound wave travels from medium A to medium B.  Medium B has more stiffness than medium A, the density remains the same.  What happens to the period?

Huygen’s principle relates to:

A sound wave leaves the transducer, travels through blood with a speed of 1560 m/s.  One second later the returning echo is received by the transducer. What was the depth of the reflector?

SPL and frequency are:

What are the units for azimuthal resolution?

Imaging transducers are:

What is the rank of all intensities from largest to smallest?

As sound travels through the body, the amplitude ____________ .

While scanning a pediatric patient the frame rate is too low.  What can the sonographer do to improve the temporal resolution?
