Comparison between two different immobilization techniques in radiotherapy for breast cancer

After a detailed comparison of the two different immobilization techniques (a. breast board immobilization; b. a combined immobilization of carnon fiber baseplate, vacuum bag and thermoplastic mask) used in radiotherapy for breast cancer, Clinic Data show that the two immobilization techniques doesn’t show any differences in X direction. In Y and Z directions, a sigle breast board is better than the other one in reducing the set-up errors. The reproducibility of using breast board for immobilization is relatively steady too.
