Fig. 2From: Potential dosimetric benefits of adaptive tumor tracking over the internal target volume concept for stereotactic body radiation therapy of pancreatic cancerBoxplots indicating the distribution of dose parameters for the target volume (3D & 4D dose) over all patients. Target volume: ITV (ITV concept); GTV (tumor tracking approach). 3D= three dimensional; 4D = four dimensional dose. ITV = internal target volume concept; track = tumor tracking approachBack to article page
