Abstract
MXA Scan analysis in accordance with an exemplary embodiment of the invention can be viewed as a process of placing points on the lateral morphometry image at the anterior, mid, and posterior positions of the inferior and superior endpoints for each vertebral body in the spinal region of interest. These point locations are then used to calculate the anterior, mid, and posterior heights of the vertebral bodies. These heights are then compared to one another and to known normal values for the heights and ratios of the heights for each vertebral body and among vertebral bodies to quantify the degree of vertebral deformity.
