title: A system for computer analysis of panorex radiographs.
abstract: Quantitative analysis of radiographs can be a very difficult and time-consuming task. Compounding this problem is a lack of standardization of films in a sequence of radiographs. Differences in magnification from film to film makes comparisons of parameters measured directly from the films virtually impossible. The system described in this paper allows for rapid comparison of non-standardized radiographs. In particular this system allows rapid measurements of alveolar ridge heights at 10 points on each side of a patient's face. Provisions allow for both mandibular and maximally studies, for reporting of means and standard deviations for each interval in a series, as well as for comparisons between intervals in a clinical sequence. Finally, graphic display allowing super-imposition of separate radiographs is possible, giving visual realization of clinically important changes in a patient's status.
