Julien Bellec, Jean-Pierre Manens, Cemil Göksu, Cécile Moisan, Pascal Haigron
2004 Lecture Notes in Computer Science  
This work involves the conception of the experimental dosimetric testing setup of an image based procedure for intravascular brachytherapy by 192 Ir seed in peripheral arteries.  ...  The method is based on the use of CT preoperative images and 2D intra-operative radiographs. Experimental dosimetric results agree with the planning and demonstrate the feasibility of the procedure.  ...  Introduction Intravascular Brachytherapy (IVB) constitutes a new therapeutic solution to avoid iterative redilations practiced after minimally invasive treatment of peripheral arterial stenoses.  ...
