Abstract
A co-registration system includes a processor circuit that receives x-ray fluoroscopy images of a blood vessel while an intravascular catheter moves through the blood vessel. The processor circuit also receives intravascular data from the intravascular catheter as the catheter moves through the blood vessel. The processor circuit generates a 2D pathway based on the fluoroscopy images. The processor circuit generates an additional 2D pathway from a 3D CT model. The processor circuit performs a co-registration between the intravascular data and the CT-based 2D pathway based on a mapping between corresponding locations of the fluoroscopy-based 2D pathway and the CT-based 2D pathway. The processor circuit performs an additional co-registration between the intravascular data and the 3D CT model based on the first co-registration and outputs the 3D model with a graphical representation of the intravascular data to a display.
