In order to use an intensity-controlled raster scan method at the new treatment facility in HIMAC, we have developed a code system dedicated to the planning of radiotherapy with the scanned 12C beam. In the code, the lateral dose distributions of the pencil beam has been expressed by a single Gaussian[for full text, please go to the a.m. URL]
