Kinect-Based Correction of Overexposure Artifacts in Knee Imaging with C-Arm CT Systems

Figure 1

(a) The Siemens Zeego C-arm CT system. The robotic arm allows free movement of the C-arm for scanning patients in standing position. (b) Typical artifacts that arise when scanning knee-shaped objects with a C-arm CT. Due to saturation, the original cylindrical shape is lost, and the front is severely affected by artifacts (window level [−1000, 1500]).
