Decoupling Respiratory and Angular Variation in Rotational X-ray Scans Using a Prior Bilinear Model

no code implementations30 Apr 2018 Tobias Geimer, Paul Keall, Katharina Breininger, Vincent Caillet, Michelle Dunbar, Christoph Bert, Andreas Maier

Data-driven respiratory signal extraction from rotational X-ray scans is a challenge as angular effects overlap with respiration-induced change in the scene.
