    Abstract: Purpose: If the horizontal plane is inconsistent between computer tomography (CT) couch and line accelerator (LA) couch, the position of the isocenter point in the radiotherapy treatment planning system (TPS) should deviate from that of it on the accelerator couch board. Then, the actual dose distribution was different from the radiotherapy plan we... Show More
