Low-dose CT denoising drops the clean-image pairs: align adjacent slices, and cone-beam CT works in image domain
Low-dose CT denoising can now be trained from adjacent slices alone: a matching network estimates inter-slice deformation and corrects the denoiser output, reaching 40.08 dB PSNR on Mayo 2016 and, for the first time, image-domain self-supervised low-dose cone-beam CT denoising.
