A study of radiotherapy planning for multiple fixed irregular field by multileaf using computed simulationgraphy

We have developed a new radiation planning method for multiple fixed irradiation by using an automatic field setup system using computed simulationgraphy. It is connected on-line with our radiotherapy treatment system so that the treatment field setting is carried out automatically after confirmation. Thus, we can get a consistent system for computed simulationgraphy from treatment planning to actual irradiation. (author)
