Abstract:
A method of therapeutic treatment of an internal structure of a living body with therapeutic radiation, said method comprising the steps of:a) implanting, at said internal structure, a sensor to identify a selected location of said internal structure, said sensor being capable of emitting a signal in response to irradiation thereof by a beam of an investigative radiation,b) scanning a region of said living body which includes said internal structure with a beam of said investigative radiation of a sufficiently low intensity to avoid causing injury to portions of said region that are adjacent to said internal structure,c) measuring said signal to determine occurrence of a maximum intensity of said signal during scanning step (b),d) associating said maximum intensity with a corresponding scanned location of said region, ande) focussing a selected intensity of said therapeutic radiation at a target determined from said corresponding scanned location of said region.
