| Abstract: | Whole central nervous system radiation is still challenging because of the need to cover a complex structures of craniospinal axis. Here, we introduced the application of CT-simulation technique in the radiotherapy of the whole central nervous system. Half-beam irradiation, full-beam irradiation, low-melting-point alloy lead shield, isoeenter irradiation and conjunction of radiation fields are used in this technique.By using 3D-TPS to optimize the plan, radiotherapy of the whole central nervous system is more accurate. |
