A type of imaging artifact closely related to reverberation is?
Characteristics of this artifact are equally false echoes, parallel and distal to the real reflector.
If sound travels at a speed of less than 1540 m/s, what will be the result?

If “snow” or a wavy line pattern is visualized in a hypoechoic area on the display, what is the most likely cause?

What artifact causes cystic structures to fill in with false echoes?
Acoustic speckle is caused by?
When mirror image artifact is present, where is the mirror reflector located?

What is the best method to correct for range ambiguity artifact?
This type of imaging artifact results in missing echo information from the display.
