A multi-slice computed tomography imaging system is provided including a source
that generates an x-ray beam and a detector array that receives the x-ray beam
and generates projection data. A translatable table has an object thereon and is
operable to translate in relation to the source and the detector array. The source
and the detector array rotate about the translatable table to helically scan the
object. An image reconstructor is electrically coupled to the detector array and
reconstructs an image in response to the projection data using a computed tomography
modeled iterative reconstruction technique. The iterative reconstruction technique
includes determining a cross-section reconstruction vector, which approximately
matches the projection data via a computed tomography model. Methods for performing
the same are also provided including accounting for extended boundary regions.
