Abstract
A novel method for imaging body tissues is disclosed wherein an ultrasonic pulse having a radially asymmetric side-lobe pattern surrounding a central focal lobe is generated. A receiver for receiving echoes of this pulse is provided which exhibits a sensitivity to echoes from the aforementioned side-lobe pattern which is relatively decreased by comparison to its sensitivity to echoes from the central focal lobe. In the preferred embodiment, square transducers which are rotated with respect to the focal axis by about 45.degree. are used to practice the disclosed method.
