Introduction: We believe the information given by a new 2D/3D low dose radiation system is useful to the spinal surgeon.

Method: This commercially developed system was evaluated over the past three years. We evaluated 150 patients, with normal controls, using two prototypes. We compared it with a CT scan for accuracy in 2D and 3D reconstruction and for radiation doses.

Results: We found various advantages of this system over CT scanning:

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.

Conclusion: his innovative method is clearly a help for both patients and surgeons.
