According to the requirements of GyroRTPS, a 3D visualization method used to display the distribution of radiotherapy dose was proposed to assist doctors to look over the dose distribution from different angles. Firstly, some preprocesses of coordinate transformation and interpolation on volume data and dosage data were discussed. Secondly, after these processing, the data for visualization was normalized according to VTK specifications. Finally, the method based on VTK to joint display dose data and human body data in 3D way was realized. The test shows that the reliability of this method and this system can better help the doctor carry on the radiotherapy.
