1. A method for expanding a field-of-view of a volumetric computed tomography scan, comprising: identifying truncated views having projection truncation and non-truncated views without projection truncation based on an average value of one or more edge channels; calculating an estimated missing projection for each of the truncated views based on at least one neighboring non-truncated view; and calculating a projection profile for each of the truncated views based on the estimated missing projection, the projection profile providing at least one of attenuation data and projection data for an area outside a field-of-view.
