Patent ID: 8296082

Claim:
A performance inspection system for an array ultrasound transducer comprising: a driver for selectively applying an electric signal to all or some of constituent channels of the array ultrasound transducer; an acoustic power measurement unit for measuring an ultrasound acoustic power emitted from individual channels receiving an identical voltage from the driver; a radiation conductance conversion unit for measuring a voltage signal applied to the individual channels at a predefined frequency, and converting the measured voltage into an ultrasound acoustic power acquired when the identical voltage is applied to the individual channels; and a channel uniformity estimation unit for estimating uniformity of a channel power at the predefined frequency 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 identical voltage by calculating an acoustic power arithmetic average value, a radiation conductance arithmetic average value, a radiation conductance dispersion, and a radiation conductance standard deviation.
