1. A system for associating anatomical information with image data, the system comprising: a computer processor configured to: obtain, via user input, an identification of a location of an anatomical landmark within a three-dimensional space formed by the image data, wherein the image data includes a first image that is of a first two-dimensional slice of the three-dimensional space and a second image that is of a second two-dimensional slice of the three-dimensional space, the second two-dimensional slice being orthogonal to the first two-dimensional slice; record the identified location in association with the image data; and display a first graphical representation of the anatomical landmark overlying a display area in which the first image is displayed and a second graphical representation of the anatomical landmark overlying a display area in which the second image is displayed; wherein the user input includes one of: an instruction for rotating the first image relative to the first graphical representation of the anatomical landmark and an instruction for rotating the second image relative to the second graphical representation of the anatomical landmark; and an instruction for rotating the first graphical representation of the anatomical landmark relative to the first image and an instruction for rotating the second graphical representation of the anatomical landmark relative to the second image.
