Fig. 2From: Quantifying the reduction of respiratory motion by mechanical ventilation with MRI for radiotherapyDiaphragm displacements were determined by translation in cranial-caudal direction aligning a region of interest (ROI) on the most cranial part of the right diaphragm dome at the anterior–posterior level of the pancreas. The ROI (fixed size, 2 × 2x15 cm) is depicted by the red box, shown in coronal (cor), axial (ax) and sagittal (sag) view of a 3DMRIBack to article page
