Fig. 2From: Comparison of sliding window and field-in-field techniques for tangential whole breast irradiation using the Halcyon and Synergy Agility systemsImaging and treatment dose. Dose contribution by imaging with the standard protocol (a, b) and by one treatment fraction (c, d) is displayed for the Synergy Agility (grey) and Halcyon unit (striped area). Results for the contralateral breast (points 1–3) are plotted on the left (a, c). The results for the ipsilateral breast (points 4–6) are shown at the right (b, d)Back to article page
