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.

Abstract: A system for non-invasive registration between a patient and a three-dimensional (3D) medical image includes a near infrared 3D camera 110 which extracts a 3D blood vessel image I2 of a patients registration target area during surgical operation; a camera position tracer 120 which traces a position of the near infrared 3D camera 110 and calculates a real world coordinate system of the 3D blood vessel image I2; a controller 130 which extracts a first blood vessel pattern from a 3D medical image I1 of the registration target area, extracts a second blood vessel pattern from the 3D blood vessel image I2, and performs position registration between the patient and the 3D medical image I1 through the extracted first and second blood vessel patterns; and a display 140 which displays a registration result calculated by the controller 130.

Abstract: A method for registering a tooth image with a tooth structure according to an embodiment includes a first registering step for registering a tooth image model obtained from a medical image taken when an object bites a bite including a marker with a bite scanning model obtained by scanning the bite, a second registering step for registering the bite scanning model with a tooth scanning model obtained by scanning a tooth shape of the object, and a third registering step for registering the tooth image model with the tooth scanning model based on the results of the first registering step and the results of the second registering step. As a result, a model including an accurate shape of tooth part difficult to obtain from a medical imaging apparatus can be easily obtained.
