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

Figure 10

An uncorrected projection is shown in (a). (b) shows the intersection lengths that have been calculated for the projection geometry as in (a). Based on these intersection lengths, the saturated projection is extrapolated. The resulting corrected projection is illustrated in (c) and can be compared to the ground truth in (d). Window levels (a), (c), and (d): [0, 8]. Window level (b): [0, 300].
