Abstract

We investigated the added value of skin markers in 566 electronic portal images (EPIs) in 48 breast cancer patients treated with tangential fields. EPIs were matched to the corresponding DRRs using skin markers, anatomy, or a combination of both. Skin markers improved determination of setup errors in cranio-caudal direction.
