Claim One:
1. A method for expanding a field-of-view of a volumetric computed tomography scan, comprising: obtaining truncated and non-truncated views of an object using a CT imaging system; identifying the truncated views having projection truncation and the non-truncated views without projection truncation based on an average value of one or more edge channels over more than one view; calculating an estimated missing projection distribution for each of the truncated views based on at least one neighboring non-truncated view; calculating a projection profile for each of the truncated views based on the estimated missing projection distribution, the projection profile providing at least one of attenuation data and projection data for an area outside a field-of-view; and displaying an image of the object on a display of the CT imaging system based on the at least one of attenuation data and projection data.
