Abstract:
X-ray devices and systems are described in this application. In particular, this application describes x-ray devices and systems that are used for three-dimensional (3D) image reconstruction with uncertain geometry. The x-ray imaging system contains an arm configured to be moved around an object to be imaged, a light weight, low power x-ray source attached to the arm, an x-ray detector configured to move complimentary to the x-ray source to capture multiple two-dimensional (2D) images in a solid angle path outside of a planar arc, 3D position and orientation tracking devices configured to capture the geometric position and orientation of the x-ray source and detector when each 2D projection image is captured, and a processor configured to construct a three dimensional (3D) image from the multiple 2D images using a reconstruction algorithm. These x-ray systems are lighter, more maneuverable, and less expensive than convectional CT x-ray systems because the geometry tracking devices combined with the processor and algorithm enable e generation of 3D images without the complex, precise, heavy, and expensive mechanical system that fixes the precise geometry of each 2D projection image to a high degree of accuracy. Other embodiments are described.
