Abstract
To date, all wavelet computed tomography (CT) work has been based on the assumption of a parallel-beam geometry. The authors directly formulate wavelet CT based on the fan-beam geometry, using recently developed theory for wavelet filtering in filtered backprojection. Experiments with clinical raw projection data demonstrate the feasibility and utility of the approach.Keywords
