Optimization of intravascular brachytherapy treatment planning in peripheral arteries
2007
Computerized Medical Imaging and Graphics
Preserved Fulltext
This work deals with the treatment planning optimization for intravascular brachytherapy (IVB) in peripheral arteries. ...
The application of this optimization method to four different CT data sets including patient data, phantom and animal models showed that the treatment plan can be improved when the actual vessel geometry ...
Introduction Intravascular brachytherapy (IVB) constitutes a new therapeutic solution to avoid iterative redilations practiced after minimally invasive treatment of peripheral arterial stenoses. ...
