Based on the encouraging results of SRS and the concern about potential normal tissue toxicity from SRS, researchers developed a technique called "fractionated stereotactic radiosurgery" (FSR) or "stereotactic radiotherapy" (SRT). It combines the high-precision technology of SRS with the potential radiobiological benefits of fractionation. Examples of SRT systems include the Gill-Thomas-Cosman frame with a dental plate and strapping system and the bite plate with infrared light-emitting diodes.
Unlike the other methods, which require the use of a minimally invasive head frame, patients can be positioned with a frame that is non-invasive and re-locatable. The initial results of studies that have used SRT to treat menin-giomas have been encouraging.
