Abstract
An ultrasound calibrator apparatus and method for calibrating ultrasound equipment. The apparatus includes a pair of opposed bellows oscillatorily transferring a fluent medium back and forth through a channel with a well-defined cross-sectional area such that the flow velocity therethrough is known. A probe in communication with ultrasound equipment to be tested is submerged in a reservoir which is situated in close proximity to the channel such that the flow velocity can be measured therewith. The ultrasound equipment is then adjusted to correct the discrepancies between the known and measured velocities so as to calibrate the ultrasound equipment.
