We are also looking into going markerless, but have heard from other centres that they do still use measurements and pen marks, at least to get to a starting point. Our particular concern is regarding breasts, who are mostly treated on an incline, and although the breastboard is fixed, and the bumstop positioned, we still have to ask the patient to move up or down to get them at the correct point on the board. We have discussed measuring a point halfway between the ssn and xiphi to give us a starting point, but does anyone have any other solutions?

Do centres use pitch as the biggest indicator for patient positioning on the incline?

Any advice would be greatly appreciated, thanks
