摘要：
Because the medical CT scanner is rapidly evolving from fan-beam to cone-beam geometry, we motivate to take advantages of Noo's formula for cone-beam reconstruction with higher temporal resolution. Feldkamp el al. proposed a practical cone-beam reconstruction algorithm for full scan data collected on a circular locus in 1984. It is known that the Feldkamp-type reconstruction framework is compatible with any fan-beam reconstruction formula. Therefore, the Noo's formula can be generalized into Feldkamp-type algorithm for the satisfactory reconstruction of a volume of interest (VOI). Our method is the first attempt to combines the pseudo-lambda tomography (PLT) and Feldkamp-type algorithm together. Simulation using the 3D differentiable Shepp-Logan phantom is performed demonstrate the utility of this technique.
