A novel scheme to design the filter for CT reconstruction using FBP algorithm
BACKGROUND: 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...
