Results
The proposed method has been applied to navigate a needle along 8 planned paths to puncture a glomus jugulare tumor for two patients. It has been previously shown that the percutaneous intratumoral injection of cyanoacrylate is an effective approach to embolize head and neck paragangliomas [Giansante Abud et al.].
For both patients two needle trajectories have been planned, using a pre-operative CT. The registration [Maes et al.] with the peri-operative XperCT reconstruction took less than 8 seconds. Using the described XperGuide method, it proved to be possible to guide the needle within 5 mm of the planned path. For the first patient (female, 63 years) one additional path was planned during the intervention in order to maximally embolize the tumor, and for the second patient (female, 64 years) three additional trajectories were planned.
