Calibrating TrueBeam jaws by considering collimator walkout to improve the dose uniformity at abutting field junctions

Jaw positions on a linear accelerator are calibrated to have accurate field size values over the range of jaw positions and to have excellent junctions when matching fields. It is sufficient to have field size accuracy on the order of a millimeter for most clinical applications but good junctions re...
