VISUALIZING SURGICAL TRAJECTORIES
First Claim
1. A method of visualizing a surgical path (31, 41, 51) for a surgical tool, the method comprising:
- receiving (21);
anatomical information (14) about a position of at least one anatomical structure (32, 33, 34, 35) in a region to undergo surgery,geometric information (15) describing the surgical path (31, 41, 51), andat least one safety margin defining a minimal distance between the surgical tool and the anatomical structure (32, 33, 34, 35),defining (23) a critical segment (43, 44, 45) of the surgical path (31, 41, 51), in which critical segment (43, 44, 45) a distance to the anatomical structure (32, 33, 34, 35) is smaller than the safety margin, andproviding (24) a graphical representation (30, 40, 50) of the surgical path (31, 41, 51), wherein the critical segment (43, 44, 45) is highlighted.

Abstract
A method and system are provided for visualizing a surgical path (31, 41, 51) for a surgical tool. The method comprises a step of receiving (21) anatomical information (14) about a position of at least one anatomical structure (32, 33, 34, 35) in a region to undergo surgery, geometric information (15) describing the surgical path (31, 41, 51) and at least one safety margin defining a minimal distance between the surgical tool and the anatomical structure (32, 33, 34, 35). The method further comprises defining (23) a critical segment (43, 44, 45) of the surgical path (31, 41, 51), in which critical segment (43, 44, 45) a distance to the anatomical structure (32, 33, 34, 35) is smaller than the safety margin. Then a graphical representation (30, 40, 50) of the surgical path (31, 41, 51) is provided (24), wherein the critical segment (43, 44, 45) is highlighted.

13. A system for visualizing a surgical path for a surgical tool, the system comprising,
an input (12, 14, 15, 16) 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, and at least one safety margin defining a minimal distance between the surgical tool and the anatomical structure, a processor (11) being operative to define a critical segment of the surgical path, in which critical segment a distance to the anatomical structure is smaller than the safety margin, and to generate a graphical representation of the surgical path wherein the critical segment is highlighted an output (13) for providing the graphical representation.
