1410 poster A RETROSPECTIVE STUDY COMPARING THE REPRODUCIBILITY OF THE WINGSTEP BREASTBOARD TO THE CONVENTIONAL MT-350 BREASTBOARD IN TANGENTIAL BREAST IRRADIATION

Intrafractional baseline drift during free breathing breast cancer radiation therapy

We have previously reported that patients might slide down a breast board if an angle is used [20]. It is therefore assumed that there should be minimal patient movement in the SI direction as there was no breast board tilt in our study.…”
