Estimating the term…
The invention relates to a method for referencing a patient or a patient body part in a camera-assisted, medical navigation system comprising the following steps: the patient body part to be referenced is brought into the detecting range of a navigation system assisted by at least two cameras (5, 6), this navigation system detecting with computer support the three-dimensional, spatial positions of light marks (3), light marks (3) are generated on the surface of the part of the body to be referenced by means of a light beam (2), the three-dimensional position of the light marks (3) being determined by the camera-assisted navigation system, the three-dimensional position of the surface of the part of the body to be referenced is determined by means of the positional data for the light marks (3). The invention relates furthermore to an apparatus for implementing the method.
A method for referencing or registering a patient or a patient body part in a camera-assisted, medical navigation system comprising the following steps:
The method as set forth in claim 6 or 7, wherein said two light beams are generated by two light sources located juxtaposed or nested.
An apparatus for referencing or registering a patient or patient body part, including a medical navigation system assisted by at least two cameras, which detects with computer support the three-dimensional, spatial positions of light marks in a detection area, and means for generating said light marks on the surface of said body part to be referenced, the three-dimensional, spatial position of said light marks being determined by said camera-assisted navigation system, wherein said means for generating said light marks is a light beamer producing light reflections on said surface as light marks.
