Fig. 2From: Evaluation of the optimal combinations of modulation factor and pitch for Helical TomoTherapy plans made with TomoEdge using Pareto optimal frontsTarget volume Pareto fronts of conformity index, homogeneity index, D2 and D98 for PTV56 and PTV69. Every colour represents a single pitch and per colour the subsequent dots (dot = median value) represent a change in MF. The arrow points at increasing MF (for D98 the arrow is reversed). Dots lying on top of the black solid line are Pareto optimalBack to article page
