ABSTRACT:
An x-ray phantom provides at least two vertebral models one of which represents a case of clinically recognized deformity relevant to the evaluation of osteoporosis. The two vertebral models are mounted with respect to each other to simulate a second spine and to permit changing of the attitude and relative orientation of the vertebral models with respect to each other. The mounting may provide variable degrees of spine curvature and permit substitution of different vertebral models simulating different deformities. The vertebral models have known bone mineral densities to permit the evaluation of automatist bone density/morphometry techniques.
