An ultrasound probe obtained by arranging, on a backing, a plurality of transducers each of which comprising a piezoelectric transducer, an acoustic lens, and an acoustic matching layer provided between the piezoelectric transducerand the acoustic lens, the acoustic matching layer containing a fibrous material, and the direction of fibers in the fibrous material being perpendicular to the direction of sound waves.

Ultrasound probe

An ultrasonic probe in which two-dimensional array transducer elements are arrayed convexly both in one direction of the two-dimensional array and in the direction perpendicular to the former direction relative to the direction where an ultrasonic wave is transmitted. By switching a transducer element selecting switch circuit provided near the transducer elements, the shape of the diameter of the probe for transmitting and receiving of ultrasound and the position of the diameter are arbitrarily determined. An ultrasonic diagnostic apparatus in which a fresnel ring is formed as an diameter by a control signal to a transducer element selecting switch circuit, the number of cables for connection between the probe and the main body is decreased by bundling the transducer elements in one ring and effecting the connection, the fresnel ring is moved every ultrasonic transmission/reception cycle by the control signal to the transducer element selection switching circuit, and an object is three-dimensionally scanned with an ultrasonic beam.
