5 YEARS OF STEREOTAXIC RADIOSURGERY AT THE UNIVERSITY-OF-TUBINGEN - ACRITICAL-REVIEW OF THE METHOD

At the University of Tubingen a Linac based stereotactic system for ra diosurgery has been used since 1991. The floorstand system (SRS 200, P hillips) developed at Gainsville is used in combination with a Cosman Roberts Weels system by Radionics. The floorstand enables the gantry t o be rotated vertically and the table to be rotated in the horizontal plane. Additionally, patient's movements are reduced by the fixation o f the stereotactic ring to the stereotactic floorstand. We report our experience with the first 50 patients treated between December 1991 an d June 1995. The patients were treated with an interdisciplinary appro ach. This cooperation eases the transition from radiosurgery to other methods such as embolization, operation, and other radiooncologic trea tment options.
