Abstract	We present some extensions to the recently published "DBP-0" method which are important for making the algorithm more suitable for clinical routine. These extensions are (i) an incorporation of the slice thickness into the reconstruction process, (ii) a way of reconstructing a region of interest smaller than the FOV, (iii) the possibility to reconstruct from flying focal spot data and (iv) a frequency apodization scheme for influencing the resolution vs. noise level during reconstruction. We furthermore present an evaluation of the DBP-0 method against the approximate Weighted FBP (WFBP) algorithm in terms of resolution, noise and subjective appearance of reconstructed images.
