Radiation therapy verification in brachytherapy combining iron sulphate gel irradiation and magnetic resonance imaging (MRI).
We developed a verification method that allows the three-dimensional qualitative delineation of the dose inside an applicator during intracavitary brachytherapy using MRI of dose-dependent changes of iron sulphate. In addition to computer calculations, the verification of the dose distribution is depicted now within the applicator. Therefore one can get a qualitative information about the relative position of the applicator according to the tumor volume and the desired brachytherapy radiation volume.
