Figure 4From: Investigation of the change in marker geometry during respiration motion: a preliminary study for dynamic-multi-leaf real-time tumor trackingMaximum misalignments. Maximum misalignments are shown with respect to initial (i.e., at end-exhale) marker/tumor geometry. Note that the misalignment of ≥2.5 mm did not occur in cases with an initial marker/tumor distance of ≤2.5 cm.Back to article page
