Evaluation of a Knowledge-Based Planning Model for Ocular Tumors: Effects of Beam Energy and Mlc Size
Stereotactic planning for ocular tumors is limited by long optimization times, inter-planner variability, and patient-specific requirements for fractionation, beam energy, and machine configuration. Knowledge-based planning (KBP) can reduce planning time and...
