Abstract
An ultrasonic imaging apparatus comprises first and second ultrasonic transducers and a driver circuit for alternately driving the first and second ultrasonic transducers to transmit ultrasonic beams in directions crossing at a given target. A receiver fetches from the echo signals of the first and second ultrasonic transducers echo components corresponding to echoes reflected in the same direction as the ultrasonic transmission direction and at a predetermined angle with respect to the target. An arithmetic logic circuit processes the echo signal components to obtain an angular dependency of scattering. A monitor displays the information representing the angular dependency of scattering.
