Method for generating a simulated bidimensional image of a portion of a patient's body

A computer-implemented method for generating a simulated 2D image of a portion of a patient's body so as to help the planning of a medical intervention on said patient, by means of a graphical user interface comprising a controller configured to control the interaction between a user and the graphical user interface, said medical intervention requiring an acquisition of an effective 2D image during or after said medical intervention, said method comprising:

• receiving real 3D medical images of said portion of the patient's body, said real 3D medical images being composed of voxels,
• computing a tridimensional digital model of said portion of the patient's body based on said real 3D medical images, by means of a ray tracing algorithm, the reconstructed tridimensional digital model being referred to as body 3D model,
• displaying in the graphical user interface a three-dimensional scene comprising said body 3D model computed by means of said ray tracing algorithm, wherein the three-dimensional scene has a corresponding scene coordinate system attached thereto,
• computing angular coordinates based on a received position and a received orientation in the scene coordinate system of a selected device, said angular coordinates representing a visualization direction in the scene coordinate system,
• generating said simulated 2D image based on said computed angular coordinates by means of a ray-based algorithm comprising sampling the real 3D medical images'voxels along rays whose trajectories depend on said computed angular coordinates,
• displaying in a 2D window of the graphical user interface said simulated 2D image.
