A Concept of Verification in BRT

Dose Planned = Dose Delivered ? can not completely be answered w/o incorporating in-situ imaging and 3D-localization techniques ! If the performance of our BRT-MLC, thus the correct stepping with the correct dwell time pattern (fluence) at the correct geometrical configuration (the analogue of Gantry, Collimator, Couch Set- Up) is the appropriate (planned) can be most probably answered by applying Computational Techniques . Computational , since in BRT we have to compute firstly and on the top issues similar to a DRR, an EPID, or a Fluence profile (the Finger-Print ?), which currently are not part of our standard RTP-procedure (as it is the case in ERT-RTP-Process).
