title: Transmission blocks for lower neck and inguinal lymph node radiotherapy.
abstract: We evaluate techniques for radiotherapy to low neck and inguinal lymph nodes. Partial transmission blocks (PTBs) simplify treatment planning, daily setup, and improve reproducibility and dose homogeneity. PTBs minimize the risk for dose misadministration to critical organs. Disadvantages include doses that are potentially lower to the medial cervical lymphatics and higher to the femur. PTBs can surmount common treatment planning problems.
