Preview of intraluminal ultrasound image along longitudinal view of body lumen
A co-registration system includes a processor circuit that displays a preview intravascular image along a longitudinal view of a blood vessel. The processor circuit receives, from an x-ray imaging device, x-ray images of the blood vessel while an intravascular catheter/guidewire moves through the blood vessel. The processor circuit receives, from the catheter, intravascular data representative of the blood vessel while the catheter moves through the blood vessel. The longitudinal view of the blood vessel is generated based on the intravascular data. The processor circuit co-registers the intravascular data to an x-ray image received from the x-ray imaging device. The processor circuit generates and displays a preview intravascular image in conjunction with the longitudinal view and overlaid over another intravascular image or an x-ray image in response to a user input.
