Abstract:
Embodiments and processes of computer tomography perform tasks associated with denoising a reconstructed image using an anistropic diffusion filter and adaptively weighting an iterative instance of the diffused image based upon the product of a weight value and a difference between the iterative instance of the diffused image and the original image. In general, the adaptive weighting is a negative feedback in the iterative steps.
