ABLATION PLANNING SYSTEM
First Claim
1. An ablation planning system, comprising:
- a user interface (104) configured to permit selection of inputs for planning an ablation procedure, the user interface further configured to incorporate selection of ablation probes and one or more combinations of ablation powers, durations or parameters applicable to selected probes in the inputs to size the ablation volumes, the user interface including a display for rendering internal images of a patient, the display permitting visualizations of the ablation volumes for different entry points on the internal images; and
an optimization engine (106) coupled to the user interface to receive the inputs and configured to output an optimized therapy plan which includes spatial ablation locations and temporal information for ablation so that collateral damage is reduced, coverage area is maximized and critical structures are avoided in a planned target volume.

Abstract
An ablation planning system includes a user interface (104) configured to permit selection of inputs for planning an ablation procedure. The user interface is further configured to incorporate selection of ablation probes and one or more combinations of ablation powers, durations or parameters applicable to selected probes in the inputs to size the ablation volumes. The user interface includes a display for rendering internal images of a patient, the display permitting visualizations of the ablation volumes for different entry points on the internal images. An optimization engine (106) is coupled to the user interface to receive the inputs and is configured to output an optimized therapy plan which includes spatial ablation locations and temporal information for ablation so that collateral damage is reduced, coverage area is maximized and critical structures are avoided in a planned target volume.

9. An ablation planning system, comprising:
-
a user interface (104) configured to permit selection of inputs for planning an ablation procedure, the user interface further configured to incorporate ablation durations in the inputs to size the ablation volumes, the user interface including a display for rendering internal images of a patient, the display permitting visualizations of the ablation volumes for different entry points on the internal images, the display being configured to render internal images of a patient and provide selection controls to enable a user to select an internal image and a view of the internal image; a database (102) configured to store the internal images and information on the ablation probes to assist in determining sizes and shapes for the ablation volumes for a given planned target volume by associating power and time characteristics with the sizes and shapes of the ablation volumes; and an optimization engine (106) coupled to the user interface to receive the inputs and configured to output an optimized therapy plan which includes spatial ablation locations and temporal information for minimally needed ablation durations, so that collateral damage is reduced, coverage area is maximized and critical structures are avoided in a planned target volume.

16. A method for planning an ablation procedure, comprising:
-
displaying (502) an internal image of a patient on a display of a user interface; selecting (504) an ablation probe or set of probes for performing an ablation procedure using the user interface; selecting (506) a point or points of entry for the ablation probe or set of probes on the internal image; providing (508) information to an optimization engine for a set of inputs including the ablation probe or set of probes selected, the point or points of entry selected, time and power information to determine sizes and shapes of ablation volumes; and providing output (510) from the optimization engine an optimized therapy plan based on reducing collateral damage, maximizing coverage area and avoiding critical structures in a planned target volume. - View Dependent Claims (17, 18, 19, 20, 21)
