Abstract
Focal spot wobbling provides a means of obtaining doubled spatial sampling in third generation computed tomography (CT) scanners. In this paper, we present a reconstruction technique which makes use of the fact that the spatial sampling interval has been halved. The proposed scheme improves system resolution and reduces the amount of computation.Keywords
