What is the definition of period in ultrasound wave terminology?

Explanation:
Period is the time required for the wave to complete one full cycle. It is measured in seconds (often microseconds in ultrasound) and is the reciprocal of frequency, so T = 1/f. This is why period is not the distance of one cycle (that would be the wavelength), not the number of cycles per second (that’s frequency), and not the speed of sound (that’s the velocity of propagation). In practice, a higher frequency transducer has a shorter period, with cycles occurring more quickly, influencing timing and axial resolution.
