We propose a new strategy to improve sampling density and image resolution in micro-CT without changing hardware and without sacrificing the size of the allowable maximum field of view (FOV). Such a strategy is achieved by use of the asymmetric scanning configurations in which the center of rotation is moved to an off-center position and a reconstruction algorithm specifically developed for such configurations. We conducted numerical studies to validate and evaluate the proposed strategy, and quantitative results in these studies confirm that the proposed configurations and algorithm can significantly improve spatial resolution properties in micro-CT.
