ROC curves of the optimal effective low dose CT scan doses for VBN performance. a ROC curve of the navigation direction for central virtual targets. b ROC curve of the number of branching’s for central virtual targets. c ROC curve of the navigation direction for peripheral virtual targets. d ROC curve of the number of branching’s for peripheral virtual targets. VBN = virtual bronchoscopy navigation
