Clinical experience with an online adaptive radiotherapy for prostate cancer: successful treatment time optimization

Cone-beam-CT-guided oART is feasible in routine prostate cancer practice. Our findings indicate that a 30-minute time slot is sufficient for most adaptive prostate cancer treatments, and a median total session time of 23 minutes can be reached through workflow and imaging optimization. Clinics considering oART should note that treatment time decreases with operator experience, and targeted measures can further reduce session duration.
