Ct Image Noise and Resolution Behavior in Rc Filter-Based Projection Data Acquisition

This paper deals with the image noise behavior due to photon fluctuation in a CT system based on RC low-pass filter for projection data acquisition. The system configuration considered consists of a stationary detector ring and a rotating x-ray source with convolution-based detector fan image recons...
