24 VMAT technique and imaging on patients with breast cancer: The daily repositioning challenge

Introduction. Daily session positioning in radiotherapy for patients with breast cancer is a crucial step towards a better treatment delivery. Studies have demonstrated that the radiographers can use surgical clips of the tumoral bed as matching structures for patient repositioning. They evaluated the coverage for breast and tumoral bed volumes but excluded the lymph nodes from the studies. The purpose of this work is to evaluate the variation in the position of the isocenter and to compare the coverage of all target volumes using different matching structures and imaging techniques available.
