Simultaneous modulated accelerated radiation therapy for esophageal cancer: A feasibility study

Figure 1 Dose distributions on three axial views of one esophageal cancer case for simultaneous modulated accelerated radiation therapy (left) and three-dimensional conformal radiotherapy (right) plans.

Figure 2 Dose volume histogram of one esophageal cancer case for the simultaneous modulated accelerated radiation therapy (solid line) and three-dimensional conformal radiotherapy (dashed line) plans. SMART: Simultaneous modulated accelerated radiation therapy; 3DCRT: Three-dimensional conformal radiotherapy; PTV: Planning target volume.
