Recognized for some years as an invaluable tool in industrial and geophysical applications, acoustical holography is proving to be a viable modality in medical diagnostic procedures. The system clearly delineates portions of the body never observed b

This paper describes a unique technique (i.e., ''Siamese imaging'') for imaging quasi-vertical defects in reactor pipe weldments. The Siamese image is a bi-symmetrical view of the inner surface defect. Image construction geometry consists of two prob
