First Experiences in Intensity Modulated Radiation Surgery at the National Institute of Neurology and Neurosurgery: A Dosimetric Point of View

The National Institute of Neurology and Neurosurgery in Mexico City has acquired a Novalis(R) shaped beam radiosurgery unit. The institute is pioneer in the use of new technologies for neuroscience. The Novalis(R) unit allows the use of conformal beam radiosurgery/therapy and the more advanced modality of conformal therapy: Intensity Modulated Radiation Therapy (IMRT). In the present work we present the first cases of treatments that use the IMRT technique and show its ability to protect organs at risk, such as brainstem and optical vias.
