TY - JOUR AU - Shi, Hongli AU - Luo, Shuqian PY - 2013 DA - 2013/06/01 TI - A novel scheme to design the filter for CT reconstruction using FBP algorithm JO - BioMedical Engineering OnLine SP - 50 VL - 12 IS - 1 AB - The Filtered Back-Projection (FBP) algorithm is the most important technique for computerized tomographic (CT) imaging, in which the ramp filter plays a key role. FBP algorithm had been derived using the continuous system model. However, it has to be discretized in practical applications, which necessarily produces distortion in the reconstructed images.
