Abstract

Approaches for performing computed tomographic image reconstruction are described. In one embodiment, a full or almost full scan of scan data is acquired and a plurality of image reconstructions are performed based on the scan data, wherein the plurality of image reconstructions result in a corresponding plurality of image volumes wherein the image reconstructions use different view weighting functions. Further, the present approaches provide for combining the plurality of image volumes together to produce a final image volume.

First claim

The invention claimed is:

1. A method of reconstructing a computed tomography (CT) image, the method comprising:
acquiring a set of projection data for an imaged volume using a CT imaging system;
reconstructing at least a first intermediate reconstruction and a second intermediate reconstruction using the acquired set of projection data, wherein the first intermediate reconstruction and the second intermediate reconstruction are reconstructed using different view weightings;
