Destruction of small intracranial tumours with 60Co gamma radiation. Physical and technical considerations.
The clinical and physical conditions for the destruction of small intracranial tumours by means of multiple gamma beam irradiation are evaluated. The effects of the collimation of the single beam and the spatial distribution of 179 beams on the superimposed three-dimensional dose distribution are investigated experimentally and theoretically. Techniques for selective irradiation of tumours of various types and sizes are discussed.
