ANATOMICAL CROSS-SECTIONAL GEOMETRY AND MASS DISTIRUBTION FOR CHILDREN. FINAL TECHNICAL REPORT. VOLUME 1

This study generated anatomical cross-sectional geometry and mass density distribution of children using the x-ray computerized tomography (CT) method. Five cadaveric specimens, with age ranging from newborn to seven, were studied. Cross-sectional CT scans of these specimens were obtained at one centimeter interval from the head to the ankle joints. From these cross-sectional CT images, the outlines of each cross section and of selected anatomical components within each section were obtained by standard picture processing techniques. The mass and intertia tensors for each cross section were estimated based on a conversion from x-ray absorption coefficients of tissues appearing on a CT scan to their mass densities. A data base structure has been designed to store and retrieve the mass information. Also presented is a discretization procedure and the generation of an internal mesh which could be used for subsequent finite element analysis. Applications of this data are discussed. Volume I of this report contains the methodology and Volume II contains derived anatomical geometry and mass distribution.
