    Abstract

    Ultrasound has been widely used for detecting breast cancer in woman. Currently, full-wave inversion methods become increasingly popular as they provide better reconstructions and tissue characterizations as compared to standard imaging methods such as SAFT. One problem with full-wave inversion is the long computation time, that is proportional to the size of the image domain. To reduce computation time we developed a new 2-D redatuming method that allows to redatum the data measured on an arbitrary curved contour to a new contour enclosing a smaller spatial domain. The new method uses Hankel function decomposition to describe the measured wave field. The applicability of the proposed method is tested successfully by using a synthetic and an a real experimental example. With the experimental example, we also show an additional advantage that redatuming brings us; it allows us to relocate the receivers at the actual grid points of our computational domain.
