X-RAY POSE RECOVERY |
摘要 |
A method, system, and program product are provided for x-ray pose recovery during an endoscopic procedure. An x-ray image is taken with a C-arm at a first pose, capturing a region of an endoscope with fiducials thereon. The C-arm is moved from the fist pose to a second pose at another viewing angle while maintaining the position of the endoscope. Anotherx-ray image is taken with the C-arm at the second C-arm pose, capturing the region of the endoscope with the fiducials thereon. The location of the fiducials on each x-ray image is determined using segmentation. An iterative optimization is performed using the locations of the fiducials in the two x-ray images to form two-dimensional projections of the three dimensional curve of the region of the endoscope with fiducials thereon to determine the three-dimensional translation and rotation of the C-arm from the first x-ray pose to the second x-ray pose. |
