Title:
【発明の名称】超音波診断装置
Document Type and Number:
Japanese Patent JP2692878
Kind Code:
B2
Abstract:
An ultrasonic imaging apparatus includes an ultrasonic transducer (1) for outputting an ultrasonic beam and converting the echo of the ultrasonic beam into an echo signal, a transmitter section (6) for supplying a drive signal to the ultrasonic transducer, a receiver section (7) for receiving the echo signal output from the ultrasonic transducer and converting the echo signal into an image signal, and a coaxial cable (2) for coupling the ultrasonic transducer to the transmitter and receiver sections. The ultrasonic transducer is constituted by a two-layer ultrasonic transducer (11) having an impedance smaller than an impedance of the coaxial cable.
