摘要
To provide a method of operating a processor device to display an angiographic and an intravascular representation of a blood vessel.SOLUTION: The method comprises: generating a set of optical coherence tomography image data in response to distance measurements of a blood vessel obtained during a pullback of a probe 30 through the blood vessel using an optical coherence tomography system, the optical coherence tomography image data comprising a plurality of cross-sectional images at a plurality of positions along the blood vessel; generating a set of angiography image data using an angiography system 20 during the pullback of the probe 30 through the blood vessel using the optical coherence tomography system, the angiography image data comprising a plurality of two-dimensional images obtained at different points in time during the pullback; and generating a confidence score for each of detection of the optical coherence tomography data and co-registration between the angiography data and the optical coherence tomography data.SELECTED DRAWING: Figure 1
