Abstract
Diffraction tomography based on the back-scattered field and the concurrent use of the transmitted and back-scattered field have received little attention. Using the total scattered field may improve image resolution, which is due to an increased coverage of the wavenumber domain. Contour information (i.e. a bandpass filtered version of the image) is located in a ring of the spatial Fourier domain and can be extracted from the backscattered field only, while grey level information (i.e. a lowpass filtered version of the image) is located in a disk centered at the origin and is accessible from the forward scattered field. Therefore, using only the forward scattered field amounts to discarding some of the image data and results in images of inferior quality.
