Computed measures on computed tomograms of the head.

Abstract
Measures of [human] average parietal bone mass (APBM) and average parietal skull width (APSW) were developed using automatic image processing techniques and a special polar coordinate system. The precision of the technique is .apprx. 2%; the measures are obtained by processing 1 section of a computed tomographic head scan obtained without special apparatus. In males the APBM does not decrease with age; in females it splits into 2 groups by age, probably based on postmenopausal changes. The APSW in both males and females increases slightly with age. The clinical utility of the measures is discussed.
