Abstract: One or more devices, systems, methods and storage mediums for optical imaging medical devices, such as, but not limited to, Optical Coherence Tomography (OCT), single mode OCT, and/or multi-modal OCT apparatuses and systems, and methods and storage mediums for use with same, for viewing, controlling, updating, and emphasizing one or more imaging modalities and/or for constructing or reconstructing 2D and/or 3D structure(s) are provided herein. One or more embodiments provide at least one intuitive Graphical User Interface (GUI), method, device, apparatus, system, or storage medium to comprehend information, including, but not limited to, molecular structure of a vessel, and to provide an ability to manipulate the vessel information and/or to construct or reconstruct 2D and/or 3D structure(s) of the vessel to improve or maximize accuracy in one or more images. In addition to controlling one or more imaging modalities, the GUI may operate for one or more applications, including, but not limited to, expansion/underexpansion (e.g., for a stent) and/or apposition/malapposition (e.g., for a stent), co-registration, and imaging.

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.

Abstract: A method for processing an intravascular image including a plurality of image frames acquired during a pullback of an imaging catheter inserted into a vessel. The method includes obtaining positions of lumen borders detected in the intravascular image and positions of stent-struts detected in the intravascular image. Determining, at different positions in a range, a stent expansion value of the stent implanted in the vessel, based on the first information and the second information, wherein each image frame from image frames in which stent-struts are detected corresponds to a different position along the range. The method may also include displaying an image including positions of lumen borders and positions of the stent-struts detected and a first indicator indicating a level along the range, of the stent expansion value, with the image.

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: A method for processing an intravascular image including a plurality of image frames acquired during a pullback of an imaging catheter inserted into a vessel, the method including displaying on a graphical user interface (GUI) an image including detected results of lumen borders and at least one stent, the image including an evaluated stent expansion and an evaluated stent apposition determined from the intravascular image. The method also includes determining whether a modification to the detected results of the stent has been received by the GUI. Then, re-evaluating stent length, stent expansion and stent apposition when it is determined that the detected results of the stent has been modified via the GUI and displaying the re-evaluated stent expansion and the re-evaluated stent apposition on the GUI.
