An imaging method, comprising the steps of: acquiring projection data of an object with an imaging apparatus comprising a detector which is offset from a center of rotation, the detector capable of assuming different detector positions along an acquisition trajectory around the object; matching at least one truncated first projection from the projection data with at least one second projection from the projection data, wherein the first projection is measured by the detector assuming a first detector position and the at least one second projection is measured by the detector assuming a second detector position, the first detector position opposite the second detector position; splicing estimated projection data derived from the projection data of the at least one second projection with projection data of the first projection to generate a full, non-truncated projection data set; differentiating the non-truncated projection data set with respect to the acquisition trajectory to generate differentiated projection data; applying a filter to the differentiated projection data to generate differentiated and filtered projection data; applying redundancy weighting to the differentiated and filtered projection data to generate differentiated, filtered and weighted projection data; and back-projecting the differentiated, filtered and weighted projection data to generate volumetric data indicative of the object, wherein the redundancy weighting is restricted to pixels of the differentiated and filtered projection data that were redundantly measured by the detector when in the first and second detector position. acquiring projection data of an object with an imaging apparatus comprising a detector which is offset from a center of rotation, the detector capable of assuming different detector positions along an acquisition trajectory around the object; matching at least one truncated first projection from the projection data with at least one second projection from the projection data, wherein the first projection is measured by the detector assuming a first detector position and the at least one second projection is measured by the detector assuming a second detector position, the first detector position opposite the second detector position; splicing estimated projection data derived from the projection data of the at least one second projection with projection data of the first projection to generate a full, non-truncated projection data set; differentiating the non-truncated projection data set with respect to the acquisition trajectory to generate differentiated projection data; applying a filter to the differentiated projection data to generate differentiated and filtered projection data; applying redundancy weighting to the differentiated and filtered projection data to generate differentiated, filtered and weighted projection data; and back-projecting the differentiated, filtered and weighted projection data to generate volumetric data indicative of the object, wherein the redundancy weighting is restricted to pixels of the differentiated and filtered projection data that were redundantly measured by the detector when in the first and second detector position.
