| 1997 | Invention patented by Nassir Navab on December 30th, 1997. Abstract: A C-arm calibration method for 3D reconstruction in an imaging system comprising an imaging source and an imaging plane utilizes a planar transformation for relating voxels in a voxel space and pixels in the imaging plane, and comprises the steps of: defining a source coordinate system in reference to the imaging source; defining a normal plane in the voxel space, not including the origin of the source coordinate system and being substantially normal to an optical axis from the source to the imaging plane; defining a relationship between the source coordinate system and another coordinate system, herein referred to as a world coordinate system, by transformation parameters; identifying pixel location coordinates for a respective pixel corresponding to each voxel in the normal plane by utilizing a planar to planar transformation; storing a value of a filtered image at the respective pixel location; and accumulating contributions corresponding to a plurality of image projections so as to thereby reconstruct each voxel. |
