What parameters are used to describe both pulsed wave (PW) and continuous wave (CW) ultrasound?

The parameters that are used to describe both pulsed wave (PW) and continuous wave (CW) ultrasound include period, frequency, wavelength, and propagation speed.

Period refers to the time taken for one complete cycle of the sound wave. It is directly related to frequency, which measures how many cycles occur in one second; these two properties are inversely related. Wavelength is the distance between successive peaks of the wave and is determined by both the speed of sound in the medium and the frequency of the wave. Propagation speed is the speed at which sound travels through the medium and is influenced by the medium's density and compressibility.

These parameters are fundamental characteristics of sound waves and apply to both PW and CW ultrasound techniques, making them essential in understanding how ultrasound waves behave and are generated in imaging systems.
