Visualization of EIM simulation data on real cardiac model / 生物医学工程学杂志

ABSTRACT

Although 3D heart and torso model with realistic geometry are the basis of simulation computation in LFX Virtual Cardiac Model, the simulation results are mostly output in 2D format. Voxel mapping method is presented to solve this problem and extend the function of LFX Virtual Cardiac Model. Excitation Isochrone Map (EIM), one of the most important simulation results, was mapped from cardiac model with realistic geometry to real Visible Man cardiac model, then the EIM simulation data before and after mapping were visualized in the 4DView which is a real-time 3D medical image visualization platform. With this method, the output format of EIM simulation data of LFX Virtual Cardiac Model was extended from 2D to 4D (time is the 4th dimension) and from cardiac model with realistic geometry to real cardiac model. According to the EIM simulation data visualization results before and after mapping, the LFX virtual cardiac model shows its characteristics with more realistic and effective simulation.
