Methods and apparatus for using interlaced scans in CT imaging

This invention relates generally to computed tomographic (CT) imaging, and more particularly to methods and apparatus for boosting image resolution for relatively long duration scans. In one embodiment of the present invention, a method for collecting views for imaging an object utilizing a CT imaging system is provided. The method includes steps of: performing a first rotational scan of an object to acquire a first set of views of the object; performing a second rotational scan of the object to acquire a second set of views of the object; offsetting starting angular views of the second rotational scan relative to the first rotational scan so that the first set of views and the second set of views form a set of interlaced views; and reconstructing an image of the object utilizing the first set of views and the second set of views.
