Abstract

Medical imaging techniques such as MRI and CT can be used to retrieve 3D anatomical digital models in medical studies. However, imaging cannot be used as many times as needed due to cost and health issues. Deformation is an alternative approach to building 3D digital models, where thin-plate spline (TPS) based transformation has been commonly used. We have developed visualization software to show the TPS based transformation by morphing 3D models created from digital imaging. The programs are used to show the animated transformation to enhance the human perception of the changes in the 3D models.
