Three dimensional models have their principal part of application in the medical domain. In the medical field, a three dimensional model gives a more accurate and visually viable version of the internal organs, bone structures, blood vessels and tissue structures. Hence various algorithms and software have been developed in the recent years for accurate analysis of a medical data in the three dimensional form. Here we obtain a three dimensional model of the human vertebrae using CT scan slices. The algorithms used for obtaining the three dimensional models are marching cubes algorithm and constrained Delaunay tetrahedralization. A comparison of these two algorithms is performed. Later this model is used as a standard model which is deformed using the specifications of subject specific stereo-radiographic images, hence obtaining a personalized vertebrae model. The deformation method used is known as dual kriging. These vertebrae on stacking produces a personalized model of deformed human spine. This model can be used for effective diagnosis of the spinal deformities.
