[Pulse Dose Rate brachytherapy: optimization and place of imaging].
Pulse Dose Rate (PDR) brachytherapy presents the potential radiobiological advantages of low dose rate and the technical and radiation protection advantages of high dose rate remote afterloading technology. The different algorithms provided by the treatment planning systems allow dose rate and isodose shape optimization regarding the volumes defined by the radiologist and the radiation oncologist. The contribution of imaging together with these new optimization tools should improve brachytherapy practice and the therapeutic ratio. These new evolutions of brachytherapy will be presented here.
