Abstract

A wide variety of mechanical and ultrasonic artifacts occur during real-time scanning of the eye. These problems may be simply annoying to the ultrasonographer or lead to serious misinterpretation of the study. Artifacts must be recognized, their source or sources identified and properly corrected in order to avoid gross errors in the scan interpretation. In this section, we shall only consider the artifacts pertinent to realtime contact B-scanning of the eye which will be discussed below.
