Knowledge based planning for stereotactic radiosurgery: standardisation of volumetric modulated arc therapy based frameless stereotactic technique using a multidimensional ensemble mapping

Knowledge based planning (KBP) is an emerging technique in a radiation therapy planning. It helps to standardise the radiotherapy planning as variations in knowledge and experience of the planner can lead to large differences in the quality of radiation therapy treatment plans. This may compromise the gains achieved through modern technologies such as IMRT or VMAT. This study is attributed to standardisation of brain SRS/SRT plans in our institution. The aim of this study is standardisation of the treatment plans by minimization of the influence of individual's skill and knowledge, based on a very large library of treatment plans. Further effort will be made to reduce the planning time
