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

Figure 7

(a) The necessary surface points for the correction are selected by first disregarding the -component of the points and the intersecting X-ray. Only surface points that have the same coordinate as the trajectory line at their coordinate are selected. (b) The calculation of the curve-line intersections is performed in 2D by only regarding the - and -values.
