Abstract
An imaging system is provided including a source generating an x-ray beam and a detector array receiving the x-ray beam and generating projection data corresponding to at least a scanned portion of an object. An image reconstructor is electrically coupled to said detector array and reconstructs an image of the scanned portion of the object for a full field-of-view in response to said projection data using a dual iterative reconstruction technique. The dual iterative reconstruction technique includes reconstructing the full field-of-view using a first resolution and reconstructing a region-of-interest within the full FOV using a second resolution. A method is also provided for reconstructing an image using projection data from such an imaging system.
