New NGPS framework improves medical imaging denoising

Researchers have developed a new framework called Neighbor-Guided Patch Sampling (NGPS) designed to improve self-supervised denoising in volumetric medical imaging. This method addresses the challenge of inter-slice misalignment, which can lead to artifacts like ghosting and blurred margins. NGPS constructs neighboring supervision by searching for structurally similar patches in local neighborhoods, enabling it to leverage more of the available data without requiring explicit registration, thereby enhancing fidelity and structure-sensitive metrics in CT and MRI scans.
