Abstract
Proposed are a method of verifying matching of a surgical target, an apparatus therefor, and a system including the same, the method including: preparing a three-dimensional (3D) model including shape information about the surgical target; acquiring information about positions and postures of the surgical target and a target marker attached to the surgical target through a tracker; performing matching with the 3D model by deriving a correlation in position and posture between the surgical target and the target marker; tracking change in the position and posture of a probe tip moving along a surface of the surgical target; and generating and displaying matching verification information including a 3D graphic icon, which represents a relative positional relationship between the probe tip and the 3D model, corresponding to change in at least one of the position and posture of the probe tip.
