A new method of calibrating tomodensitometric systems for spatial distortions, developed at Laval University, is based on the 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 an object placed in a specially designed plastic cube gives a cost-effective solution. The results obtained indicate a standard error of about ±0.2 mm in each of three dimensions.
