摘要：

A method that includes diffraction effects is introduced for the tomographic reconstruction of the ultrasonic velocity distribution of an object. The reconstruction is in the spatial frequency domain and is based on two perturbation approximations to the wave equation. The two perturbation methods, small perturbation and smooth perturbation, are discussed with respect to their regions of validity. Examples of two-dimensional reconstructions based on simulated data are presented and the results discussed. © 1979.
