3D Reconstruction of a Femur Shaft using a Model and Two 2D X-ray Images
The X-ray CT scanner and the MRI system have been widely used for 3D reconstruction. Since the large size and expensive price of such devices, they are usually found in large hospitals. In many hospitals a X-ray/fluoroscopy system is necessary and cheaper. Consider the cost, labor, and radiation exposure, the 3D reconstruction of a bone or other interested 3D object from 2D X-ray images have its meaning in practice. This paper proposes a 3D reconstruction technique of a femoral shaft shape using a three-dimensional femur template model and two 2D X-ray images, which are taken in orthographical direction. The procedure can be divided into two parts, the position and orientation of the 3D template model in 2D images and the estimation of shape parameters. At the end we receive accepted result and hope to include more models.
