If the _______________ is increased, the volume blood flow increases.

n a 1D array transducer, the slice-thickness plane is focused:

There is —— indicating a wall filter that is too low. Increasing the wall filter will remove the artifact. Be careful not to set the wall filter too high, or important diastolic information may be erased.

What is the change to operating frequency if the depth is doubled?

The half of the Spatial pulse length is —— Resolution.

A sound beam encounters an interface at a 90° angle. If the speed of sound in the first tissue is 1540 m/s and the speed of sound in the second tissue is 1450 m/s, which of the following numbers most closely approximates the angle of beam transmission?

There is “bleeding” of color pixels outside of the vessel, indicating a color gain setting that is too high.

Spectral Doppler waveform (Figure ic.1) could be corrected by:

Identifying tissues with similar shades of gray equates most to which of the following?

The speed of sound in soft tissue is:
