  • Abstract
  • Look Inside

This report describes two methods of three-dimensional display of intraocular tissues obtained from a series of consecutive cross sectional (B-mode) images.

One is a line image consisting of a set of overlaid contour lines. The other is a shaded image consist-ing of a set of gradually darkened planes which is also obtained from the corresponding B-scan digi-tized images by using image processing techniques such as smoothing and Laplacian with the aid of microcomputer. The appearance of the tissue may be observed at any visual angle. Further, we can make a measurement of areas and volumes of the tissue by this system.
