  • Image guided surgery system including a unit for transforming patient positions to image positions
    Patent number: 5902239
    Abstract: An image guided surgery system includes a position detection system which has a camera unit (1) and which measures positions of markers on the patient (12) and of a surgical instrument (11). The image guided surgery system also includes a transformation unit (30) which automatically derives the mapping associated with imaging of the patient. The imaging is for example performed by way of x-ray computed tomography or magnetic resonance imaging. The transformation unit (30) is arranged to match positions on the patient (12) to positions in the image. To that end the transformation unit computes the minimum of a cost function.
