Abstract
A computed tomography apparatus ( ) for performing volumetric helical imaging acquires helical computed tomography imaging data ( ) using a tilted gantry geometry. In the tilted gantry geometry, a rotational plane of a rotating radiation source ( ) is tilted at an angle (&khgr;) with respect to a direction (Z) of linear motion of a subject. A transform processor ( ) transforms ( ) the imaging data ( ) to a zero tilt geometry. A rebinning processor ( ) rebins ( ) the transformed imaging data ( ) to a non-sheared detector window. A reconstruction processor ( ) reconstructs ( ) the transformed and rebinned imaging data ( ) to generate a three-dimensional image representation ( ). Optionally, an image transform processor ( ) transforms ( ) the reconstructed image representation ( ) with an inverse of the zero tilt geometry transformation ( ).
