Abstract
In accordance with the invention, a reliable apparatus for guiding an ablation probe to a target location inside a human body is thus provided. The apparatus allows incorporation of a conventional metal operating room table, but further comprises a substantially non-conductive separation structure positioned over the metal operating room table and underneath a horizontally oriented electromagnetic field generator. The resultant structure is adapted to support a human body in the prone or supine position over the operating table. Further support padding may also be provided. The electromagnetic field generator creates an electromagnetic field that extends through the torso of said human body positioned over the electromagnetic field generator. An ultrasound probe and ablation probe interacts with the electromagnetic field to generate positional information that is processed by a computing device to generate a graphic representation of location information on a display device.
