TY - JOUR A1 - Galonske, Kirsten A1 - Thiele, Martin A1 - Ernst, Iris A1 - Lehrke, Ralph A1 - Zylka, Waldemar T1 - Comparison of treatment plans calculated by Ray Tracing and Monte Carlo algorithms for head and thorax radiotherapy with Cyberknife T2 - Current directions in biomedical engineering N2 - This study investigates differences between treatment plans generated by Ray Tracing (RT) and Monte Carlo (MC) calculation algorithms in homogeneous and heterogeneous body regions. Particularly, we focus on the head and on the thorax, respectively, for robotic stereotactic radiotherapy and radiosurgery with Cyberknife. Radiation plans for tumors located in the head and in the thorax region have been calculated and compared to each other in 47 cases and several tumor types.
