Fig. 3From: Noninvasive cardiac radioablation for ventricular tachycardia: dosimetric comparison between linear accelerator- and robotic CyberKnife-based radiosurgery systemsDosimetric comparison between linear accelerator (LA) and CyberKnife (CK) plans. The conformity indices (a), gradient indices (b), gradient measures (c), and maximum doses 2 cm from the planning target volume in any direction (d) of the LA and CK plans are demonstrated. p-values for statistical comparisons are obtained using a paired Student’s t-testBack to article page
