Abstract:
A method for automatically determining the 3D position and orientation of a radio-opaque medical object in a living body using single-plane fluoroscopy comprising: (a) capturing a stream of digitized 2D images from a single-plane fluoroscope; (b) detecting an image of the medical object in a subset of the digital 2D images; (c) applying to the digital 2D images calculations which preserve original pixel intensity values and permit statistical calculations thereon, using (i) multiple sequential determinations of a midline of the medical object image, (ii) a plurality of unfiltered raw-data cross-sectional intensity profiles perpendicular to each sequentially-determined midline, (iii) removal of outlier profiles from each plurality of profiles, and (iv) statistically combining each plurality of profiles to estimate image dimensions, thereby to measure the medical-object image from a final estimation of image dimensions; (d) applying conical projection and radial elongation corrections to the image measurements; and (e) calculating the 3D position and orientation of the medical object from the corrected 2D image measurements.

Claim (Index 5):
The method of  claim 4  wherein the measuring step further includes applying the center, midline and bounding-box data to the unfiltered 2D image, expanding the bounding box area around the medical-object image, and up-sampling such 2D image.
