    Abstract: The present disclosure relates to the iterative reconstruction of projection data. In certain embodiments, the iterative reconstruction is a multi-stage iterative reconstruction in which different feature are selectively emphasized at different stages. Selective emphasis at different stages may be accomplished by differentially handling two or more decompositions of an input image at certain iterations and/or by differently processing certain features with respect to each stage.

    Abstract: C-arm systems and method for making and using continuous C-arm spin acquisition trajectories for dynamic imaging and improved image quality are described. In such systems and methods, a C-arm gantry, coupled to a C-arm support assembly, is adapted to retain an x-ray source and an x-ray detector. The C-arm gantry is selectively rotatable relative to the C-arm support assembly about both a C-arm axis and a pivot-axis to displace the x-ray source and the x-ray detector along a continuous C-arm spin trajectory. The C-arm system is adapted for continuous three-dimensional acquisition of data along the continuous C-arm spin trajectory including a plurality of shorts arcs and a plurality of long arcs. The C-arm system is adapted for continuous three-dimensional acquisition of data along the continuous C-arm spin trajectory to provide continuous three-dimensional imaging of dynamic processes.
