Claim One:
1. An apparatus for computed tomography image reconstruction of an object, comprising: an image processor, including: an input port configured to receive a plurality of projection images of an object acquired by an imager, each of the projection images being along a different projection angle with respect to a field of view, FoV, wherein the object resides in a bore of said imager with at least a part of said object inside the FoV; a reconstructor configured to reconstruct the plurality of projection images to generate an image with a first reconstruction algorithm or with a second reconstruction algorithm; an out-of-FoV-determiner configured to measure an amount of the object in a region between the bore and the FoV and instruct the reconstructor to employ the first reconstruction algorithm to reconstruct the image in response to the amount failing to exceed a predetermined threshold and employ the second reconstruction algorithm to reconstruct the image in response to the amount exceeding the predetermined threshold; an output port configured to output the reconstructed image.
