Figure 1From: Biological impact of geometric uncertainties: what margin is needed for intra-hepatic tumors?An illustration of the three margins designed in this study. 1) CTV applied a full respiratory motion margin in the caudal direction; 2) CTVa added a 0.3 A expansion on CTV in the caudal direction to simulate a 0.7 A margin recipe; 3) CTVb expanded CTVa by 0.5 cm in both cranial-caudal directions to simulate no motion margin recipe.Back to article page
