Optimized CyberKnife Lung Treatment: Effect of Fractionated Tracking Volume Change on Tracking Results

Figure 2

Comparing pixel density differences among real-time X-ray images of a 6-fraction case. Note: image guidance of a 6-Fractions patient. In the figure, live is the DRR image reconstructed from the CT localization image, and each sequence number is arranged as the real-time X-ray image taken in daily intervals.
