Feldkamp-Davis-Kress reconstruction algorithm is very popular for Cone-beam Computed Tomography reconstruction. It can be combined with various filters to bring satisfaction both two-dimensional and three-dimensional tomography visualisation image quality. Shepp-Logan, Ram-Lak, Cosine, Hamming, and Hann filter are investigated in this paper for the research of the most appropriate filter for each visualisation method, the two-dimensional and three-dimensional CBCT reconstruction and visualisation.
