Abstract :
We develop a new method to exploit pairs of acoustic scans of the same image with the aim of enhancing the quality of acoustic imaging. Each image pair is assumed to be co-registered with 90deg separation between the two insonification directions. Using multi-channel image restoration, the proposed approach provides significant improvement in the quality of ultrasound imaging. Enhanced images are presented, and the advantages of this new approach over presently available methods are discussed.
