Propagation speed increases as the frequency increases.

the axial resolution can be improved by decreasing the ______ or increasing the ________.

Assuming oblique angle of incidence, if the propagation speed of medium 1 is greater than the propagation speed of medium 2, what will the angle of transmission be?

SPL =

A transducer that combines sequential and phased array technologies is:

Increasing depth changes:

The focus is the:

As a general observation about media in diagnostic sonography, sound propagates faster in materials with greater:

The use of backing material:

While scanning, the sonographer decreases the line density.  The frame rate remains the same, what else changed?
