Abstract
A method for recording a scan from a series of 2D X-ray projections using a C-arm X-ray apparatus to reconstruct a region of interest. The method includes positioning the C-arm X-ray apparatus in an initial configuration and, while recording a series of X-ray projection views: translating the C-arm along a first path within a C-arm plane parallel to the periphery of the C-arm until the central ray vector extends through the virtual scan center and the region of interest is disposed within the fan beam, moving the C-arm peripherally along the orbital movement axis by at least 180° minus the fan angle, and translating the C-arm along a second path within the C-arm plane until the second limiting vector of the fan beam is tangential to the region of interest.
