Question

Consider a focused transducer with a radius of curvature of 10 cm and a diameter of 4 cm. This transducer operates at a frequency of 3.5 MHz, and transmits a pulse of duration 0.857 μs. What is the axial resolution, in mm, at the focal point of the transducer? If the axial resolution was to be improved by a factor-of-two for example, what physical or operating parameters could be changed? Explain.
