2D-3D Medical Image Registration Based on Mutual Information
Limin Luo · Journal of Biomedical Engineering Research · 2004
A 2D-3D medical image registration method based on mutual information is described. This method is applied to the rigidity registration of X-ray fluoroscopy(simulated by DRR) and CT. After preprocessing of the 3-D data,by changing the incidence angle of ray tracking, the 2D-3D registration can be done by matching the reconstructed DRR images, and this attempt receivs good result.
