Abstract:
A method for reconstructing a computed tomographic image of an object comprising the steps of:selecting an operating mode of a CT imaging system; helically scanning an object with a multislice CT imaging system in accordance with the selected operating mode to collect projection data; identifying a center view of the collected projection data for an image plane to be reconstricted; using the identified center view to select an angular range of super-views of the collected projection data that contribute to a reconstriction of an image of a desired region of the object; weighting selected rows or views in the selected angular range of super-views using helical weights to generate synthesized views of the object in the plane of reconstriction; weighting the synthesized views with scan weights; and backprojecting the weighted synthesized views to produce a reconstructed image of the desired region of the object.
