Abstract
A plurality of ultrasonic transducers of the invented probe are separated in a concentric circle pattern, separated in rows that are orthogonal to a reference line L that passes through the center of circles, and positioned line symmetrically with respect to the reference line L. The detection surface of the invented probe has a circular shape having the diameter D, and has a plurality of segments divided into a plurality of arc-shaped portions that are symmetrical with respect to the reference line L. Further a controller which has a plurality of control channels for controlling pairs of the line symmetrical ultrasonic transducers under the same conditions is provided.
