IMRT SX2

Name (ID): 2017 QADS Head Neck PS, head and neck (2017 QADS PS HN)
Plan or PlanSum ID: SX2c_145.39

This plan was created with the .5cm effective leaf size configuration.  Nine (9) static gantry positions were selected such that the beams follow the inverted V target shape in the transverse view.  Uniquie colimator rotations were selected from the beams eye view.  This case demonstrates an example of the plan qualitry gains to be achieved when enabling the .5cm effective leave size mode with a static gantry IMRT plan.  This actual case was entered in the 2017 QADS / ProKnow Plan Study and scored 6th overall and was the highest scoring static gantry plan submitted to the study.  The way the published planning goals/plan quality metric was designed put a high emphasis on target dose homogenetity rather than on more aggressive OAR sparing.
