Abstract
An articulated ultrasonic probe for endoscopic examination comprises a transducer head, for example, having one or more rows of independently actuable transducer elements extending along the surface of the probe, parallel to the axis thereof. The probe comprises an articulable section while the transducer head is journaled for rotation with respect to the tip of the probe. In use the tip of the probe is juxtaposed to a structure to be examined; the articulated section of the probe and the rotation of the transducer are controlled separately, such that the transducer elements can be juxtaposed to the structure to be examined. A series of angularly-spaced images may be formed by rotation of the transducer about its axis after articulation of the probe.
