Abstract
The present invention relates to determining optimal C-arm angulation for heart valve positioning. In order to further improve the workflow in relation with the correct positioning of a valve prosthesis, it is described to provide () a 2D image of an aortic root of a heart of a patient, wherein the 2D image comprises three cusps of the heart in a visible and distinct manner. Further, 2D positions of the three cusps are indicated () in the 2D image. An analytical 3D model of the aortic cusp locations is provided (), and the 3D positions of the three cusps are computed () based on the 2D positions and the analytical 3D model. Still further, an optimal C-arm angulation is computed () based on the computed 3D positions of the cusps, wherein, in the optimal C-arm angulation, the three cusps are aligned in a 2D image. The optimal C-arm angulation is then provided for further image acquisition steps.
