Crystal damping ______ axial resolution.

Explanation:
Damping the crystal reduces the ringing after each pulse, so the emitted ultrasound pulse ends sooner and becomes shorter in time. It also broadens the pulse’s bandwidth, adding more high-frequency content. Axial resolution depends on the spatial pulse length, which gets shorter when the pulse is shorter in time. Therefore, damping leads to a shorter spatial pulse length and improves axial resolution.
