Using a new real-time MRI navigation system with MR gradient-based tracking system, eight patients were treated by microwave surgery. The new locator system is the MR gradient-based tracking system, which can provide the real time 6-degree of freedom tracking during MR imaging and eliminate the line-of sight problem of the optical tracking system. In the all case, microwave surgery was performed successfully without significant complication. The microwave surgery using the newly developed navigation system with the MR gradient-based tracking system is a feasible and effective procedure in treatment of the liver tumor.
