SBRT for pancreatic cancer: In regard of Bohoudi et al.

We thank the authors for their response [1] and remarks on our paper, describing a strategy for online plan adaptation. The authors express their concern about residual pancreatic motion during breath-hold, which has previously been reported, and was found to be larger during inspiration breath-hold. Our described method differs from those reports in that it combines real-time MR-guidance in a sagittal plane during delivery. In addition to this, treatment is performed using video feedback to the patients, and automated beam shut-off when the target volume moves outside the preset 3 mm safety margin during the breath-hold spells [2].
