Fig. 3From: Quantifying the reduction of respiratory motion by mechanical ventilation with MRI for radiotherapySchematic overview of the diaphragm motion metrics. For DIBH the variation of average diaphragm positions during the five consecutive breath-holds was measured. For FB and RB, the diaphragm motion peak-to-peak amplitude was determined. For PBHs, the diaphragm dome positions over time were measured.
