A non invasive method for determination of lumbar spine geometry is presented. This method performs a spatial spine reconstruction by a 3D scansion of the trunk. It analyses the geometric model of the trunk surface to identify the line which divides it into two specular portions. The method furnishes a spine shape representation in the form of a 3D curve (spline) which represents also trunk rotation. The accuracy has been evaluated in some test cases and is found to be better to the accuracy of marker based methods.

Abstract
A non invasive method for determination of lumbar spine geometry is presented. This method performs a spatial spine reconstruction by a 3D scansion of the trunk. It analyses the geometric model of the trunk surface to identify the line which divides it into two specular portions. The method furnishes a spine shape representation in the form of a 3D curve (spline) which represents also trunk rotation. The accuracy has been evaluated in some test cases and is found to be better to the accuracy of marker based methods.File in questo prodotto:
