Abstract

An ultrasonic probe for mechanical scan-type is disclosed which comprises one or a plurality of ultrasonic transducers (20) mounted on a supporting member (14). One or more of the transducers are devided electrically or mechanically. The supporting member is located in a container (2) with ultrasonic wave propagating medium. The supporting member (14) rotates or swing in the container and ultrasonic beam emanated therefrom scans object in sector form. The divided transducers are selectively driven in commonly or separately in accordance with display mode.
Another embodiment which includes a plurality of ultrasonic transducers each having different focal length is also disclosed.
