ULTRASONIC PROBE

Abstract: according to one embodiment, an ultrasonic probe includes a transducer group and an acoustic lens. the transducer group include a plurality of ultrasonic transducers. the acoustic lens is provided on a transmitting/receiving side of the transducer group and includes a first curved surface and a second curved surface corresponding to an acoustically effective aperture of at least the transducer group. the acoustic lens is higher in sound speed than a first medium in contact with the first curved surface and higher in sound speed than a second medium in contact with the second curved surface or a soft tissue in contact with the second curved surface. the first curved surface is a concave surface and facing the transmitting/receiving side. the second curved surface is a concave surface and opposing the first curved surface. the first curved surface is different in radius of curvature from the second curved surface.
