20140114180 | LIVE 3D ANGIOGRAM USING REGISTRATION OF A SURGICAL TOOL CURVE TO AN X-RAY IMAGE - A method, system, and program product are provided for providing a live 3D image of a body lumen. The 3D shape of a flexible surgical tool in the body lumen is determined using optical shape sensing. An x-ray image is taken of the body lumen, with at least one of the body lumen and the surgical tool being radiopaque. The determined 3D surgical tool shape is registered to the x-ray image. | 04-24-2014 |

20140206994 | ACCURATE VISUALIZATION OF SOFT TISSUE MOTION ON X-RAY - A method, system, and program product are provided for accurately visualizing soft tissue motion on an x-ray image. Real time ultrasound images are registered to an x-ray image space. A point of interest is defined. Motion of the selected point is determined from the real time ultrasound images. The determined motion is applied to the selected point on the x-ray image. | 07-24-2014 |
20140334744 | REMOVAL OF ARTIFACTS FROM AN EM FIELD GENERATOR FROM A 3D SCAN - A method, system, and program product are provided for removing artifacts from an EM field generator from a rotational 3D scan. The method comprises: preoperatively, characterizing the artifacts from the EM field generator over a range of rotational positions of an x-ray source and detector; intraoperatively, determining the position of the EM field generator relative to the x-ray source and detector; and removing the preoperatively characterized artifacts for the determined relative position of the EM field generator from current x-ray image | 11-13-2014 |
