Abstract
A performance inspection system for an array ultrasound transducer includes: a driver for selectively applying an electric signal to all or some parts of constituent channels of the array ultrasound transducer; an acoustic power measurement unit for measuring an ultrasound acoustic power emitted from individual channels receiving the same voltage from the driver; a radiation conductance conversion unit for measuring a voltage signal applied to each channel although the driver applies different voltages to the individual channels, and converting the measured voltage into an ultrasound acoustic power acquired when the same voltage is applied to the channels; and a channel uniformity estimation unit for estimating uniformity of the acoustic power value acquired by the radiation conductance conversion unit or uniformity of acoustic power values of the individual channels measured under the same voltage.
