Verification of field match lines in whole breast radiation therapy using cherenkov imaging

Often in radiation therapy, the treatment of breast cancer includes irradiation of the supraclavicular nodes to discourage further spread. Two irradiation sites are used, including 1) the entire breast (whole-breast/tangent (TAN) fields) and 2) the supraclavicular (SCV) field [1] –[3] where both fields meet at a single isocenter. (Using a dual iscoentric technique is also common, though this study examines the use of one isocenter [4].) In these cases, the fields meet at the isocenter, forming what is known as the field junction, or anterior field match line.
