Comprehensive and Detailed Explanation From Exact Extract:
Damping material is applied to the back of the piezoelectric crystal to absorb energy and shorten the pulse duration. Shorter pulse durations reduce spatial pulse length, which directly improves axial resolution by enabling better separation of structures along the beam path.
According to sonography instrumentation reference:
“Greater transducer damping results in shorter pulse duration and improved axial resolution but reduces sensitivity.”
Therefore, the correct answer is D: Improved axial resolution.
