METHOD OF USING THE NOVEL POLYMER GEL FOR MAGNETIC RESONANCE IMAGING (MRI) VALIDATION

摘要

Novel normoxic N-(Hydroxymethyl) acrylamide (NHMAGAT) polymer gel dosimeters for MRI scanning are introduced for radiotherapy planning system. The composition of the NHMAGAT polymer gel and method of making the NHMAGAT polymer gel dosimeter are disclosed. The dosimeters are irradiated with Varian Rapid Arc linear systems at different absorbed doses. The results show that the percent depth dose and 2D plan dose distribution of NHMAGAT polymer gel dosimeters are in a good agreement with the ionization chamber measurements and CT planned dose distribution, respectively.
