Abstract

The determination of absorbed dose distribution is an essential requirement for good treatment planning in Boron Neutron Capture Therapy. In this therapy, the high non- uniformity of the spatial distribution of absorbed dose and the complexity of dose components have created the necessity of a 3D dose determination with good spatial resolution and without perturbing the radiation field with the dosimeters themselves. The goal of this work is that of attaining the possibility of constructing tissue-equivalent phantoms which act by themselves as dosimeters: after exposure they can be analyzed by means of a nuclear magnetic resonance imaging systems, and the 3D distribution of absorbed dose can be determined with good spatial resolution. the discrimination between the contributions of thermal neutrons and (gamma) - rays to the absorbed dose will be possible too.
