In an exemplary embodiment, the processing techniques of computerized x-ray tomography are applied to improve resolution transverse to the depth direction, for example with the use of compound ultrasonic scanning. In this way, an improved preliminary image for representing non-directionally scattering...http://www.google.fr/patents/US4407163?utm_source=gb-gplus-shareBrevet US4407163 - Method for processing ultrasonic echo signals of both directionally reflecting as well as non-directionally scattering objects, particularly for ultrasonic image processing in the field of substance or tissue investigation
