What kind of artifact may appear on B-scan ultrasound images?

The choice of reverberation artifact as the correct answer is based on the characteristic behavior of ultrasound waves when they interact with structures in the eye. In B-scan ultrasound, reverberation artifacts occur when sound waves reflect between two highly reflective surfaces, such as the posterior lens capsule and the anterior surface of the retina. This repeated reflection creates echoes that can display as multiple lines or echoes on the ultrasound image, often giving the impression of false structures or additional layers that do not actually exist.

Reverberation artifacts are particularly important to recognize because they can potentially confuse the interpretation of B-scan images, leading to misdiagnosis or misinterpretation of ocular conditions. Understanding this artifact is crucial for sonographers as it impacts the accuracy of the ultrasound examination.

Other types of artifacts, such as reflection, noise, and shadowing, can also appear in ultrasound imaging but have different origins and effects. For instance, reflection artifacts stem from the interface between different mediums, noise refers to random signals that distort the image quality, and shadowing generally indicates the presence of a dense object that absorbs ultrasound waves, obscuring structures deeper than the object. In this context, recognizing the unique characteristics and implications of reverberation artifacts is vital for effective ultrasound imaging and
