Conventional methods of localization and immobilization have provided a certain level of accuracy and precision in target delineation and treatment delivery. The availability of dedicated CT and images from PET, MR and US have introduced the radiation therapy community to extensive information to enhance the treatment planning and delivery processes. It also has aided in the development of image-guided tools to further assure accurate and precise delivery. Additionally, 3D conformal and IMRT treatments require sub-millimeter accuracy. This can only be achieved using optically guided system. Principles, procedures and experience with these tools will be discussed.
