Abstract
A diagnostic ultrasonic probe for use in body cavities has at its tip an ultrasonic transducer array, which has a layered structure wherein a flexible circuit board, an electric circuit, a backing material, a piezoelectric element array, an acoustic impedance matching layer and an acoustic lens are formed atop another on a supporting member. The electric circuit includes at least one of amplifiers for amplifying echo signals from ultrasonic transducers, switches for switching over between sending the echo signals from the ultrasonic transducers and receiving drive signals for exciting the ultrasonic transducers, a multiplexer for selective-switching between the echo signals as well as between the drive signals, an A/D converter for converting the echo signals from an analog form to a digital form, and a D/A converter for converting the drive signals from a digital form to an analog form.
