Figure 16

Modelling of the trunk shape during brace building. During brace building a careful modelling of the trunk shape is made either on the cast mould or on the PC screen. In this figure the correction of circumferences (left) and shapes (right) of a single patient with a right thoraco-lumbar curve is reported. On the left there are the original (red) and corrected (blue) horizontal sections of the body at the level of the horizontal lines reported in the middle body shape, where the original laser scan of the trunk is represented. On the right the frontal contour of the original (red) and corrected (blue) body shapes are reported, while inside these lines, in grey, there is the final trunk shape from which the brace is going to be built.
