Abstract

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.

Claims

1. A system for computer-assisted planning for a surgical ablation procedure, comprising:

a processor; and

a display operably coupled to the processor and controllable by the processor to display a user interface, the user interface including;

at least one image based on patient image data;

a shape selection user interface configured to receive a user input enabling a user to select an ablation shape from a plurality of ablation shapes stored in a database;

at least one other ablation parameter related to the user selected ablation shape;

a preview of selectable probes, wherein at least one of the selectable probes is a displayed probe which is configured to generate the user selected ablation shape;

a rotation interface that rotates the at least one image, the user selected ablation shape, and the displayed probe in a synchronized manner in response to a user input; and

a temporal interface that updates the user selected ablation shape over-time in response to a user input, the temporal interface including a slider element configured to be positioned at a desired point along a time scale to view the ablation shape corresponding to the desired point along the time scale.

2. The system according to claim 1, wherein the patient image data is selected from the group consisting of x-rays, ultrasound, computed tomography (CT) scans, magnetic resonance imaging (MRI), and combinations thereof.

3. The system according to claim 1, wherein the at least one other ablation parameter is selected from the group consisting of a probe diameter, a frequency, an ablation length, an ablation diameter, a temporal coefficient, a shape metric, a frequency metric, and combinations thereof.

4. The system according to claim 1, wherein the user selected ablation shape is displayed over the at least one image.

5. The system according to claim 1, wherein the user selected ablation shape is displayed as a three dimensional graphic rendering.

6. The system according to claim 1, wherein the user selected ablation shape is displayed as part of a probe image.

7. The system according to claim 1, wherein the at least one image is displayed as a three dimensional image and the selected ablation shape is superimposed over the at least one image.
