Fully automatic online geometric calibration for non‐circular cone‐beam CT orbits using fiducials with unknown placement
Abstract Background Cone‐beam CT (CBCT) with non‐circular scanning orbits can improve
image quality for 3D intraoperative image guidance. However, geometric calibration of such …
