A new voxel mapping method enhances the LFX Virtual Cardiac Model, enabling 4D visualization of cardiac electrophysiology simulation data. This improves the realism and effectiveness of virtual heart modeling for research.

Area of Science:

  • Computational modeling and simulation
  • Medical imaging and visualization
  • Cardiac electrophysiology

Context:

  • Current LFX Virtual Cardiac Model outputs simulation data primarily in 2D.
  • Realistic 3D heart and torso models are used for computation.
  • Bridging the gap between simulation data and anatomical models is crucial.

Purpose:

  • To present a voxel mapping method for extending LFX Virtual Cardiac Model simulation output.
  • To enable 4D visualization of Excitation Isochrone Maps (EIM).
  • To map EIM data from a geometrically realistic model to a real anatomical model.

Summary:

  • A voxel mapping technique was developed to transfer EIM data from a realistic geometry cardiac model to the Visible Man cardiac model.
  • The mapped EIM data was visualized in the 4DView platform, allowing for real-time 3D medical image visualization.
