1. A method for indicating accuracy of image segmentation in a patient model, the method comprising:
creating a three-dimensional bone surface model of a portion of a patient's bone from imaging data;
determining accuracy of a surface's representation of a transition from bone to soft tissue in the three-dimensional bone surface model based on a first gradient, wherein the first gradient is determined between a first point, which is on a surface of a bone in the three-dimensional bone surface model, and a second point, which is spaced from the surface of the bone, along a line extending from the surface of the bone at the first point; and
marking, on the three-dimensional model, an indication of the accuracy of the surface's representation of the transition;
wherein the first gradient is a first gradient.
