Abstract:
Provided is a method of controlling an angiocatheter route using OCT. The method includes inserting a catheter into a blood vessel of a test object, injecting a dye into the blood vessel and capturing an X-ray image, acquiring a three-dimensional OCT image of a vicinity around the catheter, determining a position of the catheter within the blood vessel using the three-dimensional OCT image and the X-ray image, and displaying the position of the catheter on the X-ray image.
