1. A method for generating an image of an object, the method comprising: acquiring projection data at one or more projection views, wherein the projection data is acquired along a circular scan trajectory; generating a corrected projection dataset by: computing a correction term for a subset of the projection data to generate a weighted filtered projection dataset corresponding to the subset; for a remainder of the projection data, applying a ramp filter to the remainder of the projection data and weighting the ramp filtered remainder of the projection data to generate a ramp filtered weighted projection dataset; combining the weighted filtered projection dataset and the ramp filtered weighted projection dataset to generate a corrected projection dataset; and backprojecting the corrected projection dataset along one or more projection rays associated with one or more of the projection views, to generate a reconstructed image of the object.
