Beam Width Artifact

The lateral width and elevation width of the ultrasound beam cause a decrease in lateral resolution resulting in occurrence of beam-width artifacts

The lateral width and elevation width of the ultrasound beam, respectively, cause a decrease in lateral resolution and the occurrence of beam-width artifacts.
The blue square object within the scanning plane is correctly identified in the center of the beam.
However, because of the elevation width of the beam, the green circular object outside of the imaging plane is incorrectly positioned within the scanning plane.

2. Tilting of the probe to open the Aorta (A5C) reveals anerysmal enlargement of the aortic root picked up by the beam in A4C as if a mass occurring in the RA.

a. Adjust focal zone
