Projection space denoising with bilateral filtering and CT noise modeling for dose reduction in CT

PURPOSE: To investigate a novel locally adaptive projection space denoising algorithm for low-dose CT data. METHODS: The denoising algorithm is based on bilateral filtering, which smooths values using a weighted average in a local neighborhood, with weights determined according to both spatial proxi...
