Outline of Angiography/IVUS Image Data Fusion

Imaging setup, visualization, quantitative analysis

  1. In a standard biplane angiographic system, a square grid of markers is attached to both image intensifiers, a field of view is selected, and biplane system parameters are recorded.
  2. Biplane angiographic system is calibrated using a calibration phantom, e.g., a ball of a known diameter.
  3. IVUS catheter is inserted in the coronary vessel of interest, when in the distal position, a single pair of biplane angiographic images is recorded.
  4. IVUS pullback is recorded using a constant speed pullback device.
  5. Input angiographic and IVUS images are processed and automatically visualized in 3D from interactively determined viewpoints, quantitative analysis is facilitated.
