Visualizing surgical trajectories
First Claim
1. A method of visualizing a surgical path for a surgical tool, the method comprising:
- receiving;
anatomical information about a position of at least one anatomical structure in a region to undergo surgery,geometric information describing the surgical path,at least one safety margin defining a minimal distance between the surgical tool and the anatomical structure, andat least one surgical tool restriction defining at least one geometric parameter for the surgical path necessary for a surgical tool to perform a procedure,defining a critical segment of the surgical path, the critical segment having a distance to the anatomical structure smaller than the safety margin,defining a restricted segment of the surgical path, in which the restricted segment of the surgical path does not meet the surgical tool restriction, andproviding a graphical representation of the surgical path, wherein the critical segment and the restricted segment are highlighted on the graphical representation of the surgical path, wherein said critical segment and said restricted segment are highlighted differently from each other.

Abstract
A method and system are provided for visualizing a surgical path for a surgical tool. The method comprises a step of receiving anatomical information about a position of at least one anatomical structure in a region to undergo surgery, geometric information describing the surgical path and at least one safety margin defining a minimal distance between the surgical tool and the anatomical structure. The method further comprises defining a critical segment of the surgical path, in which critical segment a distance to the anatomical structure is smaller than the safety margin. Then a graphical representation of the surgical path is provided, wherein the critical segment is highlighted.

12. A system for visualizing a surgical path for a surgical tool, the system comprising,
an input for receiving: -
anatomical information about a position of at least one anatomical structure in a region to undergo surgery, geometric information describing the surgical path, at least one safety margin defining a minimal distance between the surgical tool and the anatomical structure, ands at least one surgical tool restriction defining at least one geometric parameter for the surgical path necessary for a surgical tool to perform a procedure, a processor configured to define a critical segment of the surgical path, the critical segment having a distance to the anatomical structure smaller than the safety margin and a restricted segment of the surgical path, in which the restricted segment of the surgical path does not meet the surgical tool restriction, wherein the processor is further configured to generate a graphical representation of the surgical path wherein the critical segment and the restricted segment are highlighted differently from each other on the graphical representation of the surgical path, and an output for providing the graphical representation.
