title: Theoretical study for use of Leksell's stereotactic frame in radiosurgery.
abstract: The authors examine all the problems connected with the use of Leksell's frame. These problems were studied specifically for the treatment of artero-venous malformation of the brain using small fields and movement therapy of a 10 MV linear accelerator. The technique allows the administration of high radiation doses (25-30) Gy into a very small target within a fraction. In this way the surrounding tissue receives a low dose. The treatment was initially simulated with a dummy. The dosimetry gives an accuracy of +/- 1.5%. This study has been able to resolve all the theoretical and practical problems demonstrating the feasibility of the project which has already been put into effect.
