| 内容記述 | In order to use an intensity-controlled raster scan method at the new treatment facility in HIMAC, we have developed a novel code system dedicated to the planning of radiotherapy with the scanned 12C beam. The variation of beam-spread in the direction lateral to the beam axis and non-collinearity of the beam by scanning magnets in the horizontal and vertical directions are considered in the beam model. Inverse planning techniques are implemented in the software in order to obtain the uniform biological dose distribution within the planned target volume (PTV) as well as reduce the dose delivered to the organ at risks (OARs) delineated on clinical CT images. The scan trajectory is determined so that the path length will be minimized by applying a fast simulated annealing algorithm for scan trajectory optimisation. Furthermore, the extra dose inevitably delivered to the irradiated site is integrated into the inverse planning process to shorten the treatment time. The code also copes with the planning for intensity modulated ion therapy (IMIT). Treatment plans were produced for several CT images of the patients treated at HIMAC. The beam steering file is produced with the software in which the position and particle fluence for each raster point is written following the optimised scan trajectory. The reliability of the developed code has been confirmed through the irradiation experiments according to the beam steering file at the secondary beam line in HIMAC. | |||||
