ABSTRACT:
Ultrasonic transmission imaging apparatus utilizing a pair of focused, large aperture transducers colinearly aligned and facing one another on opposite sides of a target. The receiving transducer and transmitting transducer are positioned to have a common focal point within the target. The transmitting transducer is energized by a continuous noncoherent noise source, and ultrasonic images are formed from the intensity modulation of the transmitted ultrasound at the receiving transducer.
