Ablation planning system

A computer program comprising machine executable instructions for execution by a computational system controlling a medical instrument, wherein the medical instrument comprises a user interface comprising a display;

• wherein execution of the machine executable instructions causes the computational system to:
• receive an anatomical segmentation identifying a location of an anatomical structure;
• receive a target zone segmentation identifying a location of a volume at least partially within the anatomical segmentation;
• and
• display planning graphical user interface using the display;
• wherein the planning graphical user interface comprises a first panel configured for rendering a cross sectional view of the anatomical segmentation and a cross sectional view of the target zone segmentation;
• wherein the planning graphical user interface further comprises a second panel configured for displaying a rendering of a first three-dimensional model of the anatomical segmentation and the target zone segmentation;
• wherein the planning graphical user interface further comprises a third panel configured for rendering a second three-dimensional model of a remaining portion of the target zone segmentation;
• wherein the planning graphical user interface further comprises an ablation selector configured for providing a user-selectable ablation zone descriptive of a volume at least partially within the remaining portion;
• wherein execution of the machine executable instructions further causes the computational system to repeatedly:
• receive the ablation zone from the ablation selector;
• and
• update the remaining portion by removing the ablation zone from the remaining portion.

A method of operating a medical instrument, wherein the medical instrument comprises a user interface, wherein the user interface comprises a display,

• wherein the method comprises:
• receiving an anatomical segmentation identifying a location of an anatomical structure;
• receiving a target zone segmentation identifying a location of a volume at least partially within the anatomical segmentation;
• and
• displaying a planning graphical user interface using the display;
• wherein the planning graphical user interface comprises a first panel configured for rendering a cross sectional view of the anatomical segmentation and the target zone segmentation;
• wherein the planning graphical user interface further comprises a second panel configured for displaying a rendering of a first three-dimensional model of the anatomical segmentation and the target zone segmentation;
• wherein the planning graphical user interface further comprises a third panel configured for rendering a second three-dimensional model of a remaining portion of the target zone segmentation;
• wherein the planning graphical user interface further comprises an ablation selector configured for providing a user-selectable ablation zone descriptive of a volume at least partially within the remaining portion;
• wherein the method comprises repeatedly:
• receiving the ablation zone from the ablation selector;
• and
• updating the remaining portion by removing the ablation zone from the remaining portion.
