<p>A method for positioning the relative pose of an hollow needle with a wire partially hold by the hollow needle and a bone of a creature, comprises the steps: i) capturing into a computer an X ray image of the hollow needle inserted into a bone region; where the X-ray image comprises at least an image of - the real bone (1.1); - the hollow needle (1.2) and of - the wire (1.3) inserted inside of the hollow needle (1.2); ii) opening a 3D virtual model of the bone region, where the bone region comprises - a virtual bone model (2.1); - a virtual hollow needle (2.2) and - a virtual wire (2.3); iii) assessing a 3D virtual exact position of the said needle (3.2) respect to the said bone (3.1) region by freely moving, rotating and zooming the said 3D virtual objects (3.1, 3.2, 3.3). This method does not require any additional bulky equipment that has to be held and maintained in the operation room.</p> |
