The results of computer simulated experiments in three-dimensional microwav
e tomography in scalar approximation are presented. The gradient method is
employed to solve three-dimensional high-contrast microwave tomographic pro
blems. A computer model for full-scale three-dimensional imaging has been c
reated. Three-dimensional tomographic images of mathematical models of the
human torso were obtained. Significant differences between two-dimensional
and three-dimensional cases are emphasized. Some illumination schemes which
can be applied in the three-dimensional case are discussed. A dependence o
f image quality on the number of vertically placed transmitters has been de
monstrated. The computer simulation showed that three-dimensional full-scal
e human torso dielectrical properties images can be produced with acceptabl
e computational time.
