How do you get rid of artifacts in ultrasound?
Since artifacts aren’t reproducible in more than one or two panes, you can get rid of the artifact by making use of several techniques. Side-lobe artifacts occur when smaller lobes of energy encounter a strong reflector, which creates echoes that appear to originate from the ultrasound’s central beam.
How are mirror image artifacts prevented in ultrasound?
When necessary, they can be prevented by decreasing the TGC near in the near gain, or by changing the beam’s angle and switching windows. Mirror image artifacts are produced when the ultrasound’s sound waves are reflected, and, as a result, travel back to the transducer by taking an indirect path. Thankfully, recognizing this artifact is easy.
