A filtered backprojection algorithm with ray-by-ray noise weighting
PURPOSE: This paper derives a ray-by-ray weighted filtered backprojection (rFBP) algorithm, based on our recently developed view-by-view weighted, filtered backprojection (vFBP) algorithm. METHODS: The rFBP algorithm directly extends the vFBP algorithm by letting the noise weighting vary from channe...
