Irradiation and dosimetry of Nitinol stent for renal artery brachytherapy.
This study was conducted to assess the suitability of (48)V radioactive stent for use in renal artery brachytherapy. A nickel-titanium alloy Nitinol stent was irradiated over the proton energy range of up to 8.5 MeV, to obtain (48)V. The depth dose distribution analysis of the activated stent was done with TLD-700 GR in a Perspex phantom. We investigated a unique mixed gamma/beta brachytherapy source of (48)V. For a 10mm outer-diameter (48)V stent, the average measured dose rate to vessel was 37 mGy/h. The dosimetry results of the (48)V stent suggest that the stent is suitable for use in renal artery brachytherapy.
