CO-REGISTRATION OF INTRAVASCULAR DATA WITH ANGIOGRAPHY-BASED ROADMAP IMAGE AT ARBITRARY ANGLE, AND ASSOCIATED SYSTEMS, DEVICES, AND METHODS

摘要

A co-registration system includes a processor circuit in communication with a display, an x-ray fluoroscopy imaging device, and an intravascular catheter/guidewire. The processor circuit receives, from the x-ray fluoroscopy imaging device, x-ray fluoroscopy images of a blood vessel while the intravascular catheter/guidewire moves through the blood vessel. The x-ray fluoroscopy images comprise a view of the blood vessel at a first angle. The processor circuit receives, from the intravascular catheter/guidewire, intravascular data representative of the blood vessel while the intravascular catheter or guidewire moves through the blood vessel. The processor circuit generates a roadmap image of the blood vessel based on x-ray angiography data. The roadmap image comprises a view of the blood vessel at a different, second angle. The processor circuit co-registers the intravascular data to the roadmap image. The processor circuit outputs, to the display, the roadmap image and a visual representation of the intravascular data overlaid thereon.
