Abstract:
1. A method for presenting an interventional instrument in a 3D data set of an anatomy to be treated, comprising: recording the 3D data set of the anatomy before introducing the interventional instrument; recording fluoroscopy x-ray images of the anatomy from two different angulations after introducing the interventional instrument; determining a spatial position of the interventional instrument by the x-ray images; generating a 3D model of the interventional instrument from the x-ray images; fusing the 3D model of the interventional instrument with the 3D data set of the anatomy; reproducing a 3D hologram from the fused 3D data set for presenting the 3D model of the interventional instrument in the 3D data set of the anatomy; and repeatedly reproducing the 3D hologram in real time to follow an application of the interventional instrument for the presentation.
