Abstract: Detecting a vessel region in multiple angiographic image frames and defining a direction that perpendicularly intersects a longitudinal direction of the vessel region to improve co-registration between two imaging modalities. Motion of the vessel region is then detected based on the direction that intersects the longitudinal direction of the vessel region by evaluating positions of the vessel region in the multiple angiographic image frames. The method includes defining an area based on the detected motion and the detected vessel region, detecting a marker of an imaging catheter disposed in the vessel region within the area and performing co-registration based on the detected marker.

Abstract: There is provided medical devices and methods of use. The medical device comprising: an elongated tube; a balloon disposed over the elongate tube having at least one drug and at least one fluorescent agent on an outer surface of the balloon; an optical probe at the distal end of the elongate tube comprising an optical fiber configured to guide illumination light coming from a light source and an optical member configured for fluorescence imaging; and one or more detectors configured for fluorescence detection. The probe may comprise an optical probe for fluorescence imaging, and optionally an additional probe component for structural imaging or physiological sensing. The method can be particularly useful for determining whether sufficient dose of a drug has been transferred from a balloon to the lumen.

The method comprises: acquiring a multimodality image of a blood vessel, the multimodality image includes first image data co-registered with second image data collected simultaneously by scanning an inner wall of the blood vessel with light of two or more wavelengths transmitted through the catheter; analyzing the first image data to identify a characteristic feature of the blood vessel; detecting, based on the characteristic feature of the blood vessel, a potential blind spot location of the second image data in the multimodality image; and displaying on a display device the multimodality image with a marker showing the potential blind spot location of the second image data in relation to the first image data.

Abstract: A method for processing angiography image data by using an imaging catheter path that is directly detected from the angiography data as a co-registration path or using detected marker locations from the angiography data to generate a co-registration path. If the acquired angiography data includes synchronized cardiac phase signals and a predetermined quantity of angiography image frames not including contrast media, then a directly detected imaging catheter path is used as the co-registration path. Otherwise the co-registration path is determined based upon detected marker locations from the angiography image data.
