Requires in vivo validation before clinical use; leaves open translation of phantom SAR performance to tissue.
The cap-choke catheter antenna provides an efficient design for intracavitary microwave ablation with low power reflection.
Lin et al. (1996) studied Diseases responsive to thermal ablation therapy. Cap-choke catheter antenna was evaluated on Specific absorption rate (SAR) distribution and power reflection coefficient. The cap-choke catheter antenna yielded desired specific absorption rate distributions and was efficient, with a measured power reflection coefficient of 2% in tissue equivalent phantom modeling materials.
