摘要：
This paper presents an efficient reconstruction algorithm for three-dimensional scattering objects. The algorithm is an extension of previous work for the two-dimensional one, and is based on an optimization procedure. From the computer simulations, the proposed method is shown to yield satisfactory results, and to not be so sensible to the presence of noise. (C) 2001 John Wiley & Sons, Inc.
