RoboCT: The State and Current Challenges of Industrial Twin Robotic CT Systems

Twin robotic X-ray computed tomography (CT) systems enable flexible CT scans by using robots to move the X-ray source and the X-ray detector around an object’s region of interest. This allows scans of large objects, image quality optimization and scan time reduction. Despite these advantages, robotic CT systems still face challenges that limit their widespread adoption. This paper discusses the state of twin robotic CT and its current main challenges. These challenges include optimization of scanning trajectories, precise geometric calibration and advanced 3D reconstruction techniques.
