Figure 1: Methodology for manual co-registration of PET and CT angiography.

Figure 1:

PET and CT angiography were manually co-registered by first aligning the blood pool (left) using key points of reference. The PET activity was subsequently aligned in the aorta to the CT angiography (middle). The final refinement of co-registration was performed according to landmarks around the coronary arteries as well as the aortic and mitral valves.
