Figure 1

The correlation error (a) and frequency of correlation error (b) of one fraction is shown with the tumor position output of correlation model (solid line), the tumor position of X-ray imaging from the ModelPoints.log file (stem points) in three directions, respectively. The time intervals between the X-ray imaging is about 40 seconds.
