How does increasing the frequency affect image resolution in ultrasound?

Explanation:
Increasing the frequency shortens the ultrasound wavelength, which improves the system’s ability to distinguish small distances along and across the beam. This tightens the spatial pulse length and allows finer detail to be resolved, boosting both axial and, with tighter focusing, lateral resolution. The trade-off is that higher frequency attenuates more quickly, so deeper tissues are harder to image. Overall, raising frequency enhances image resolution.
