Abstract
Disclosed is a novel CT denoising method using deep learning to boost the image signal-to-noise ratio for improved disease detection in patients with acute ischemic stroke (AIS). This method reduced the original CT image noise significantly better than BM3D, with SNR improvements in GM, WM, and DG by 2.47×, 2.83×, and 2.64× respectively and CNR improvements in DG/WM and GM/WM by 2.30× and 2.16× respectively. Scans denoised by the proposed model are shown to be visually clearer with preserved anatomy. The disclosed deep learning model significantly reduces image noise and improves signal-to-noise and contrast-to-noise ratios in 380 unseen head NCCT cases.
