The range is the measurable set of numbers between the limits of the maximum and minimum values.

Range gating utilized the selection of a returning ultrasound wave according to its depth by receiver activation at the appropriate time delay. The ultrasonic signal is selected by the range gate.

The dynamic range in signal processing is the range between the minimum low intensity and maximum high intensity signals that a system is capable of displaying.

The range resolution is the ability to determine the depth of reflectors.

Arrays are spatial arrangements of transducers or transducer elements.
