Radiation has been used as a form of treatment for tumors since almost 100 years. But with advances in technology there is now a focus on treating the tumour aggressively while saving all surrounding normal structures. This is possible when there is maximum radiation delivered to the tumour and minimal radiation to the surrounding tissues.
Stereotactic RadioSurgery is a non invasive, image guided; precise surgery. 3D images of the tumour are taken before and during the procedure. High density precisely directed radiation beams are then guided to the tumour while sparing the adjacent tissues. This ensures better tumour control, better survival rates and lesser side effects.
Varian Medical Systems (USA) and BrainLAB (Germany) have developed the NovalisTx which is today the most versatile and powerful RadioSurgery system.
