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....
