Which type of amplification enhances tissue differentiation in ophthalmic ultrasound?

The type of amplification that enhances tissue differentiation in ophthalmic ultrasound is S-shaped amplification. This amplification curve is designed to improve the visibility of structures by enhancing contrast in areas of lower intensity while compressing higher-intensity signals. The S-shaped function effectively accentuates differences between tissues that may otherwise be difficult to discern, allowing for greater differentiation between various pathologies or anatomical structures in ophthalmic imaging.

This method of amplification is particularly beneficial in ophthalmic ultrasound because it allows sonographers to create clear and detailed images that can help in diagnosing conditions such as retinal detachments, tumors, or other ocular anomalies. By enhancing the contrast in the images, S-shaped amplification provides a more accurate depiction of the tissue interfaces, which is crucial for clinical assessments and decisions.
