Computerized reconstruction of an anatomical structure based on digitized sections. Preliminary study.

The authors propose a technique of spatial reconstruction of serial sections using the modern methods of computer graphics. The technical problems encountered and the duration of the classical Born method render the proposed technique difficult to apply as a routine procedure. The results of this work show that computer assisted image reconstruction could be used in daily routine work only when appropriate software programs and sufficient memory capacity become available to allow rapid image restitution. With the technique described in this paper, the reconstruction and display of a single image require 7 to 8 h of computer time.
