ABSTRACT:
A method for evaluating cancellous bone from a density pattern of the cancellous bone obtained by irradiating the cancellous bone with a radiation wherein trabeculae of the cancellous bone are analyzed based on a power spectrum obtained by a Fourier transformation of the density pattern is provided.
Furthermore, a method for evaluating cancellous bone from the density pattern of the cancellous bone obtained by irradiating the cancellous bone with radiation, wherein the density pattern is determined by irradiating the radiation substantially vertically against the main trabecula of the cancellous bone and the degree of the bone atrophy of the cancellous bone is evaluated by using the area (.SIGMA.GS) of the density pattern and/or the value (.SIGMA.GS/D) obtained by dividing the area (.SIGMA.GS) by the bone width (D) of the cancellous bone.
