Claims

[Scope of utility model registration request]

(1) A casing containing a propagation medium i for propagating ultrasonic waves is attached to the surface of a transducer array formed by arranging a plurality of strip-shaped transducers in a concave shape, and the focus of the acoustic beam from the transducer array is is set at or near the tip of the housing, and when the transducer array is linearly scanned, the object is sector scanned. An ultrasonic probe characterized by having a lens attached to it to focus the sound wave beam in the thickness direction.

(2) The scope of the utility model registration claim characterized in that the acoustic lens is a concave lens whose cross section has the shape of a plano-concave lens when the speed of sound in the lens is faster than the speed of sound in the propagation medium. The ultrasonic probe according to item 1.

(3) A request for registration of a utility model characterized in that the acoustic lens is a concave lens whose cross section has the shape of a plano-concave lens, if the speed of sound in the lens is faster than the speed of sound in the propagation medium. An ultrasonic probe within the range of item 1 above.
