Abstract

A new method of calibrating tomodensitometric systems developed at Laval Univer-sity is described. This is based on the basic concept that each image represents parallel projection geometry for the sectional plane it represents. Scale affinity and inherent distortions are mathematically modeled. A series of parallel consecutive images taken of object placed in a specially designed plastic cube gives a cost-effective solution. The obtained results indicate a standard error of around ± 0.2 μm in each of three dimensions.
