It may be used only by radiation therapeutical experts under medical supervision in rooms which are suitable for the operation of computers. In addition the planning of interstitial radiosurgery by implanting radioactive seeds inside of the target volume (Brachytherapy) and the planning of stereotactic approaches (Stereotaxy) will be supported.
