Abstract
A method for reconstructing an image of an object utilizing a cone-beam volumetric computed tomographic imaging apparatus includes helically scanning the object with a radiation source utilizing the cone-beam volumetric computed tomographic imaging apparatus, selecting radiation beams emitted by the radiation source passing through a pixel P, a Tam-window, and a Katsevich window, filtering the selected projection data, and reconstructing an image of the object utilizing the filtered selected projection data including projection data within the Katsevich window and outside the Tam-window.
