Aliasing occurs when the velocity reaches more than____ of the PRF - Correct-
answer-1/2
Contrast can be used to _____ the Doppler signal in order to obtain an adequate
display - Correct-answer-highlight
When using a contrast media the sonographer must _____ acoustic power -
Correct-answer-decrease. Higher power will burst the bubbles of contrast
Type of artifact caused by the regular periodic spacing of elements within the
