Geometrical Errors Correction in Truncated Scans via Locally Linear Embedding with A Phase Correlation Metric
RPI ID: 2023-087-301 Innovation Summary: This technology applies locally linear embedding (LLE) techniques to correct motion artifacts in computed tomography (CT) imaging. It models patient movement during scans and reconstructs accurate images by embedding motion data into the reconstruction algorithm. The system improves image clarity and diagnostic...

Motion Correction with Locally Linear Embedding for Helical Photon-Counting CT
RPI ID: 2022-041-301 Innovation Summary: This invention introduces a novel motion correction framework for photon-counting computed tomography (PCCT) using locally linear embedding (LLE). The method addresses motion artifacts by modeling the high-dimensional projection data as a low-dimensional manifold and applying LLE to recover motion-free representations....
