Abstract
S92 ESTRO 38DVH parameters and optimization objectives were extracted from archived DVH reports.Data were analysed in SPSS. ResultsIn 10.7% (n=19) of cases the auto-plan was directly accepted for treatment.In 46.9% (n=83) of cases, MUs were scaled before accepting the auto-plan.In 40.1% (n=71), the auto-plan was optimised further.In 2.3% (n=4) of all cases, the auto-plan was rejected entirely and a new plan was made manually.We could identify the following reasons for manual adaptations: Bowel loop: 14.7% of plans (n=26), a bowel loop was near the PTV.In 4 cases MU were scaled and 22 cases were optimised further.
