REAL-TIME DISPLAY OF TISSUE DEFORMATION BY INTERACTIONS WITH AN INTRA-BODY PROBE

摘要

In some embodiments, data sensed and/or operational parameters used during a catheterization procedure are used in the motion frame-rate updating and visual rendering of a simulated organ geometry. In some embodiments, measurements of and/or effects on tissue by sensed and/or commanded probe-tissue interactions are converted into adjustments to the simulated organ geometry, allowing dynamic visual simulation of intra-body states and/or events based on optionally partial and/or non-visual input data. Adjustments to geometry are optionally to 3-D positions of simulated data and/or to simulated surface properties affecting geometrical appearances (e.g., normal mapping). Optionally, the organ geometry is rendered as a virtual material using a software environment (preferably a graphical game engine) which applies simulated optical laws to material appearance parameters affecting the virtual material's visual appearance. Optionally, physiology, motion physics, and/or other physical processes are simulated based on live inputs, as part of assigning geometrical adjustments to the simulated tissue.
