Abstract: Embodiments relate to a method for tracking a location of a surgical tool based on a radiographic image, which includes: by a photography system, photographing a surgical tool having a physical marker frame composed of three or more marker bands; by an information processor, detecting a center point of each marker band in the photographed image; and by the information processor, estimating a three-dimensional location of the surgical tool based on a distance between the detected center point and a center point of a true marker band, and a tracking apparatus for the same.
