Abstract: In radiation therapy for cancer treatment, inverse planning approaches?wherein optimization tools are used to automatically generate treatments?are gaining in both popularity and clinical acceptance. While intensity modulated radiation therapy has been the primary focus of optimization-based inverse planning research in the literature, technological advances in the delivery of stereotactic radiosurgery mean that radiosurgery treatments can now also benefit from optimization-based treatment planning. We investigate several optimization approaches for the Leksell Gamma Knife Perfexion radiosurgery treatment device (Elekta AB, Stockholm, Sweden) and find that optimization can improve on clinical deliveries as well as enable new treatment possibilities for Perfexion, including continuous delivery and homogeneous dosages.
