Figure 2

Plot of the prostate movement during one course of Cyberknife® treatment in the left-right- (a), anterior-posterior- (b) and inferior-superior-direction (c). The movement was measured using two orthogonal x-ray projections and the implanted gold markers. The different colours indicate the different fractions (F): 1st F black, 2nd F red, 3rd F magenta, 4th F blue, 5th F green. It should be noted that during the actual treatment the position of the treatment table was adjusted after each measurement.
