From: Spatial accuracy of dose delivery significantly impacts the planning target volume margin in linear accelerator-based intracranial stereotactic radiosurgery

Fig. 3

Box and whisker plots of the planning target volume (PTV) margins (\(\:{C}_{i}\); i = X, Y, Z) for intracranial single-fraction stereotactic radiosurgery at 22 institutions. The margin was derived from 3D-SS analysis of the dose delivery accuracy and from residual setup errors reported by Ong et al.26 and Zhang et al.20. Notation: *p < 0.05; **p < 0.01; ***p < 0.001.
