FIGURE 7. Future applications for molecular-anatomic cardiac image fusion. Volume-rendered phantom study of biplane 3D vessel reconstruction of x-ray angiography is fused with 18F-FDG PET phantom scan containing simulated defect. Such displays also could be used with 3D CT angiography and SPECT or PET data to compare perfusion and viability defects with extent of stenosis. Phantom data acquired at Ottawa Heart Institute, Ontario, Canada.
