    摘要: Disclosed is a system and method for enabling user preview and control of the size and shape of an electromagnetic energy field used in a surgical procedure. The disclosed system includes a selectively activatable source of microwave surgical energy in the range of about 900 mHz to about 5 gHz in operable communication with a graphical user interface and a database. The database is populated with data corresponding to the various surgical probes, such as microwave ablation antenna probes, that may include a probe identifier, the probe diameter, operational frequency of the probe, ablation length of the probe, ablation diameter of the probe, a temporal coefficient, a shape metric, and the like. The probe data is graphically presented on the graphical user interface where the surgeon may interactively view and select an appropriate surgical probe. Three-dimensional views of the probe(s) may be presented allowing the surgeon to interactively rotate the displayed image.
