A substantial part of the Workshop is devo- ted to practical exercise in ventriculography- guided, and CT, MRI and angiography-guided

stereotaxis where the brain target is reached either through a burrhole or by means of exter- nal irradiation. To achieve the aim of the Work- shop the number of participants will be limited to 50.
