Breast Cup Immobilization Device II (GCC 1047)

The study is designed to assess the accuracy of patient breast reproducibly using the revised BCID. This study would provide data for target verification and quality assurance to eventually allow treatment of breast cancer patients for either a TBB or accelerated partial breast irradiation. The BCID is a low-risk device similar to immobilization devices used routinely in radiotherapy for other disease sites.
