Poster Summary:  This novel technique uses conformal photon and electron beam arrangement for hypofractioned partial breast. This approach can be effective or superior to other methods such as static field IMRT or VMAT for medially located, superficial targets, achieving dose conformality and OAR avoidance. It has been clinically demonstrated to a reliable and efficient 3D technique.
