SU-F-18C-15: Model-Based Multiscale Noise Reduction On Low Dose Cone Beam Projection.


PURPOSE To improve image quality of low dose cone beam CT for patient positioning in radiation therapy. METHODS In low dose cone beam CT (CBCT) imaging systems, Poisson process governs the randomness of photon fluence at x-ray source and the detector because of the independent binomial process of photon absorption in medium. On a CBCT projection, the… (More)
