Abstract
To obtain small rim thickness of normal brain tissue against high dose which is concentrated at target region, the authors developed the Photon Knife system (PKS) for stereotactic radiosurgery with linear accelerator which is 6MV x-rays. The beam of PKS was specially designed for the trans-multi-arc beam (TMAB) combined the multi-arc beam to avoid the limitation of arc beam selection as dependence of critical organ around target lesion. The TMAB was processed with right decubitus of patient position to obtaion a proper beam selection. When the beam selection was a TMAB, the coordinate should be represented the geometric rotation system with dose matrix to obtaining the stereotactic dose distribution. The authors converted the parameter of the couch and gantry angle in trans-multi-arc system to that of multi-arc beam and used an intermediary parameter of cubic coordinate system. Furthermore, this study showed the determination of depth from skin to any dose matrix using schematic cubic contours.
