30 May 2003Multidimensional registration of x-ray image and CT image
We present a methodology for alignment of X-Ray image and CT image, based on chamfer 3-4 distance transform and simulated annealing optimization algorithm. The proposed approach firstly segments object’s structure from X-Ray image. Using projection model and optimization method, we deduce the correct projection matrix. This method is also integrated into medical intra-operation, dealing with the data set acquired from 3D image workstation and active navigation.
