Fig. 2From: Novel 4D-MRI of tumor infiltrating vasculature: characterizing tumor and vessel volume motion for selective boost volume definition in pancreatic radiotherapyExample 4D-MRI coronal images at (a). end-of-inhalation (EOI), (b). mid-ventilation, and (c). end-of-exhalation (EOE) bins; (d-f) show the motion trajectories derived from the tumor (red) and involved vessel (green) in the superior-inferior, anterior-posterior and medial-lateral directionsBack to article page
