How many dimensions are depicted in a B-scan image?

A B-scan ultrasound image provides a two-dimensional representation of structures within the eye. In this imaging technique, sound waves are emitted and reflected back from the various tissues, allowing for the visualization of the internal ocular structures, such as the retina, vitreous body, and any lesions or abnormalities present.

In a B-scan, the depth information is represented on one axis, while the lateral position is captured on the other, effectively creating a 2D view of the ocular anatomy. This is crucial for diagnosing conditions such as retinal detachments or tumors, as it allows practitioners to assess both the vertical and horizontal planes of ocular structures simultaneously.

This two-dimensional capability is what distinguishes the B-scan from other imaging modalities or techniques that may present in one, three, or even four dimensions, which would incorporate time or additional spatial information.
