Abstract Background Image-guidance systems allow accurate interfractional repositioning of IMRT treatments however these may require up to 15 minutes. Therefore intrafraction motion might have an impact on treatment precision. 3D geometric data regarding intrafraction prostate motion are rare we therefore assessed its magnitude with pre- and post-treatment fiducial-based imaging with cone-beam-CT CBCT . Methods 39 IMRT fractions in 5 prostate cancer patients after 125I-seed .
