Radiographic Determination of Mass of Inertial Tensors of Anatomical Segments.

Abstract

ANCO is investigating the use of radiographic techniques to determine properties of anatomical segments - mass, center of gravity, and the inertial tensor. Three orthogonal projections (x-ray photographs) through the segment will determine these properties if sufficiently high energy x-rays are used so that attenuation is independent of atomic number and just dependent on mass density. This occurs above a few hundred keV energy. The intent of this study is to investigate the practicality and potential accuracy of the method. Progress to date is described herein. Keywords: Exposure time; Radiation dosage; Photodensitometers; Computer programs.
