Three-dimensional display of ultrasonic images using a fly's-eye lens

In order to form a three-dimensional image from a set of two-dimensional cross-sectional ultrasonic images, a simple method making use of a fly's-eye lens in proposed. The depth perception obtained from the reconstructed image using the fly's-eye lens is analysed and an optical configuration that maximizes the depth perception is devised. With this configuration, the synthesis of a three-dimensional image is performed by using a simple object. Results of the experiment show clearly the three-dimensional aspect of the reconstructed image.
