Abstract:
A medical diagnostic imaging system, comprising:a C-arm unit having an x-ray source for generating x-rays and a receptor for obtaining image exposures from received x-rays, said C-arm unit moving said x-ray source and receptor along an image acquisition path between at least first and second exposure positions, said C-arm unit rotating about a central axis; x-ray source and receptor brackets mounting said x-ray source and receptor, respectively, to said C-arm unit, said x-ray source and receptor brackets moving at least one of said x-ray source and receptor in a radial direction toward and away from said central axis of the C-arm unit to maintain a desired distance between said x-ray source and receptor; an image processor collecting a series of image exposures from said receptor including at least first and second image exposures obtained while said x-ray source and receptor are located at said at least first and second exposure positions, respectively, said image processor collecting position data for multiple exposure positions corresponding to said series of image exposures, said image processor constructing a three dimensional (3D) volumetric data set based on said series of image exposures and said position data for said multiple exposure positions; and a display displaying images based on said 3D volumetric data set.
