Abstract
We discuss 3D bone surface reconstruction from a set of few digital X-ray projections acquired with a mobile C-arm system. We first show the C-arm calibration and the modeling of its mechanical deformation. Then a 3D shape reconstruction method based on elastic registration of a statistical model with a set of few projections (2 to 5) is discussed and applied to a lumbar vertebra.
