Take home message for IGRT modality/frequency: Image-guidance for partial breast irradiation

• IGRT still under-used in breast (compared to other sites)

• Weekly images are not an efficient way to reduce uncertainties ➢ Consider an offline (NAL / eNAL) protocol ➢ Optimise image quality vs dose

• Daily imaging is the only way to address both systematic and random uncertainties
