Figure 3From: Investigation of the change in marker geometry during respiration motion: a preliminary study for dynamic-multi-leaf real-time tumor trackingThe marker/tumor misalignments as a function of respiratory phase for the 25 distances. A statistically significant difference in misalignment was observed between the 30%-70% respiratory phases and the 10% respiratory phase (P<0.05, Mann–Whitney U-test). The horizontal line represents the median value for each respiratory phase.Back to article page
