Figure 2From: A novel scheme to design the filter for CT reconstruction using FBP algorithmThe original signal and its different reconstructed versions. (a) The original signal, (b) the reconstructed signal after DFT and IDFT using θ k =(2k π/N)0.8, (c) the reconstructed signal after the identical DFT, IDFT and a filtering process using the designed filter between DFT and IDFT.Back to article page
