Whole Abdominal Irradiation: Dose distributions for Reg 2.5 (“regular” delivery with a 2.5 cm field width; upper row) and DJDC 5.0 (Dynamic Jaw/Dynamic Couch delivery with a 5.0 cm maximum field width; lower row). Note the slightly worse lateral dose penumbra in DJDC 5, for example in the left lobe of the liver (dark arrowhead) and the increased incidence of hotspots in DJCD (light arrowheads).
