Reductions in radiation exposure of x8 to x10 fold in 2D, and x800 to x1000 in 3D. It gives data from standing imaging compared with supine in a CT scanner. It allows imaging of the skeleton from head to foot, which in CT imaging demands excessive radiation. It allows surface reconstruction from head to foot It can be used with a force plate to indicate gravity forces It, uniquely, can give a view of the skeleton from the top It can measure thoracic cage volume It can assess the effects of bracing When combined with other non-invasive methods of measurement, can help to define operative procedures Overall it provides a new approach to assessing spinal deformity both in the horizontal plane and in volumetric measurement.
