The required margins to cover inter- and intrafraction GTV motion were 17mm and 6mm, respectively.

The shorter the treatment time, the smaller the margins needed to cover for the GTV movement during an online adaptive MRgRT dose-escalation strategy for intermediate risk rectal cancer. When time intervals between replanni
