Evaluating the Adequacy of Giro-Couch to Support Prone Breast Boost Irradiation Using IMRT Technique With IGRT.

Treatments are applied with the subject in the supine position, in \~50 Gy per treatment (\~2GY per fraction), over a period of five to six weeks. Energy in use is usually 6-15MV photons. Following the whole breast irradiation, a boost dose is given to the lumpectomy cavity, in order to further reduce the local recurrences in the immediate vicinity of the treated breast. The boost dose is usually applied with electrons, 6-18MEV. Sixteen Gy is the usual dose, 2 Gy/Fx, for 8 fractions.
