Claim 5:
6. The method for obtaining an image biomarker that quantifies the quality of the trabecular structure of bones, according to claim 5, wherein calculating the bone fraction map comprises:
eliminating heterogeneities in a scale of intensities of the high-resolution MRI trabecular image that contains the ROI that was delimited,
applying a statistically-based local threshold algorithm, which determines an intensity value of marrow in a of each voxel based on the statistics of the nearest neighbour,
adjusting the threshold of the high-resolution MRI trabecular image and enabling the scaling of the intensity of the voxels partially occupied by trabecula, and
producing a bone volume fraction map.
