Fig. 1From: Simultaneous integrated boost (SIB) radiation therapy of right sided breast cancer with and without flattening filter - A treatment planning studyMeasurement setup for verification of the low dose. Transversal (top) and coronal (bottom) CT slice of the phantom used for verification of the dose in the low dose region. The isocenter was placed such that the high dose area of the PTV (red) was inside the phantom to maintain phantom scatter and the dose region corresponding to the medial part of the contralateral breast (green) was located in the active area of the MatriXX Evolution. Isodoses are given in Gy. The orange box shows the ROI used for evaluation of the low dose regionBack to article page
