  • METHOD FOR SIMULATING A DEVICE DEPLOYMENT
    Publication number: 20250148366
    Abstract: A method for training a machine learning system, including: based on at least one image dataset representing at least one portion of the hollow structure, calculating a signed distance field of each portion and calculating at least one geometrical parameter of each portion; generating a deployed in-use representation of the device by computing contact forces between the device and each portion based on the signed distance field and by applying these contact forces to a geometrical representation of the device; and training the machine learning system with each calculated geometrical parameter as an input and the corresponding deployed in-use representation as an associated target output, the obtained trained machine learning system being configured to receive as input at least one geometrical parameter and provide as output the deployed in-use representation of the device.

  • Simulation of the deployment of an endoprosthesis in real time
    Patent number: 12070273
    Abstract: A device for medical imaging by X-ray is provided. More specifically, it relates to the simulation of the deployment of an endoprosthesis in order to assist the surgeon in an endovascular surgical procedure. The invention makes use of a single 2D image in order to determine certain characteristics of a simplified model of the endoprosthesis: 2D positions, and deployment value of the stents; to determine the inherent rotation of at least one stent; then to determine the deployment of a model representing the structure of the stents, initialized on the basis of the preceding steps, in a 3D model of a vascular structure.
