Paper Abstract

Optical Fourier analysis has been used to estimate quantitatively the bone tissue structure. The two dimensional power spectrum of the light transmitted through the trabecular pattern on a radiograph of the femoral neck was analyzed. Measurements were taken along the compressive and tensile stress trajectories in the femoral neck. When the trabecular architecture changed, significant changes in the high frequency region of the power spectrum were detected. Quantitative processing was used to define parameters characterizing the trabecular architecture. Significant differences were found between the trabecular pattern in bones of normal subjects and in bones of osteoporotic patients.
