LOCAL X-RAY BONE DENSITY TOMOGRAPHY METHOD |
| abstract |
A method for determining the bone mineral density of a tissue for a patient who acquires x-ray projection images of the patient and reconstructs a volume of interest (VOI) that includes a bone-like tissue which is imaged inside each of the projection images. A subset of voxels for anterior material is identified in the VOI having a known density value. For each voxel in the VOI, a voxel mass attenuation coefficient is calculated based on an estimated calculated proportion of the anterior material and bone-like tissue at the voxel level. An iterative process compares the calculated voxel mass attenuation coefficients with attenuation coefficients measured from the reconstructed VOI and updates the calculated proportion and voxel mass attenuation as a function of the comparison. The invention further relates to mineral density information for bone type tissue displays in the updated proportion and voxel attenuation calculations. |
