Since 2012, the VirtuTRAXTM instrument navigator (GE Healthcare, USA) is being used as a navigation system for guiding radiofrequency ablation (RFA) needles in Japan. Fifteen patients were treated using RFA needles guided by VirtuTRAXTM. The short clip method was performed in the following way: after measuring the distance between the body surface and the target position of the needle tip, and considering 3 cm for attachment, a bracket was fixed to the RFA needle at the calculated position. The positional gap caused by the deflection of the RITA needle was small. These gaps were sometimes large for patients undergoing cool-tip RFA because of weak stiffness. However, the positional gap became small and useful for 7 patients on whom the short clip method was used during RFA.
