Radiation dosimetry using Fricke-infused gels and magnetic resonance imaging.
We have witnessed the advancements of MRI-Fricke-infused gel dosimetry since its commencing in 1984. Over the years, many efforts have been spent to improve the method's efficacy, i.e., to improve its dose-response sensitivity, reproducibility and measurement accuracy. In this article, we give a review of the development of this relatively new dosimetric method. An example of applying this method to gamma knife stereotactic radiosurgery dose distribution mapping is also given.
