Axial resolution improves with higher frequencies due to which type of pulses?

Explanation:
Axial resolution comes from how long the ultrasound pulse is in space along the beam (the spatial pulse length). When the pulse is shorter, echoes from two closely spaced reflectors along the axis are told apart more easily. Higher frequency makes the wavelength smaller, which reduces the spatial length of the pulse. With a shorter pulse, the system can distinguish two structures that are closer together along the beam path, so axial resolution improves. In short, higher frequencies produce shorter pulses, leading to better axial discrimination.
