Abstract
A method and apparatus for performing 2D to 3D registration includes an initialization step and a refinement step. The initialization step is directed to identifying an orientation and a position by knowing orientation information where data images are captured and by identifying centers of relevant bodies. The refinement step uses normalized mutual information and pattern intensity algorithms to register the 2D image to the 3D volume.
Claims1
A method for registering two-dimensional image data with three-dimensional image data of a body of interest, said method comprising:
- acquiring the three-dimensional image data having first patient orientation information;
- acquiring the two-dimensional image data having second patient orientation information;
- and
- generating a digitally reconstructed radiograph that substantially corresponds to the two-dimensional image data using the three-dimensional image data and the first and second patient orientation information.
