Abstract
An x-ray computed tomography system for helical scanning, translates a patient as projections of the patient at various beam angles are obtained and employs a detector array having multiple rows displaced along the direction of translation. The intensity signals from the multiple rows are combined to produce a composite projection having an improved beam profile along the translation direction. The composite projection is generated by adding together intensity signals obtained for detector elements in each column, at a given beam angle, and for related columns measuring rays having angles differing by x radians or an integer multiple thereof. The intensity signals are selected so that their points of acquisition cluster closely about the position of the desired slice plane.
