Patent ID: 7995819

Claim:
A method for displaying a location of a point of interest on a 3-D model of an anatomical region of a person, comprising: determining a first projection line extending from a first point on a first 2-D image to a first position of an X-ray source, the first point being in a 2-D coordinate system of the first 2-D image, the first position being in the 3-D coordinate system of an image acquisition system; determining a second projection line extending from a second point on a second 2-D image to a second position of the X-ray source, the second point being in a 2-D coordinate system of the second 2-D image, the second position being in the 3-D coordinate system of the image acquisition system; determining the point of interest in the 3-D coordinate system of the image acquisition system that corresponds to an intersection point of the first and second projection lines; determining a position of the point of interest in a 3-D coordinate system of the 3-D model of the anatomical region; and displaying the 3-D model of the anatomical region on a display device, the 3D model having a marking icon at the point of interest.
