INFORMATION ACQUISITION DEVICE USING ACOUSTIC WAVE

摘要

PROBLEM TO BE SOLVED: To provide an information acquisition device such as an ultrasonic diagnostic device which improves a routing property of a cable by eliminating the need to prepare a wire for a high voltage or a high current, a connector for a high voltage and the like.SOLUTION: A probe part 105 of the information acquisition device comprises: a multi-channel transducer 101 including a plurality of elements; and a front end circuit 102 connected to the transducer for supply of a bias voltage to the transducer and exchange of a transmission/reception signal. A main body part 107 comprises: a power distribution section 113 for distributing power from a power source part; and a transmission/reception circuit 108 for exchanging a transmission/reception signal with the front end circuit. A connection part 106 including a plurality of wires 104 and 111 supplies a bias voltage from the power distribution part to the front end circuit.
