Abstract: The present disclosure provides to process intravascular ultrasound (IVUS) images to identify key frames such as the proximal key frame, a distal key frame, and a minimal key frame from the IVUS images based on the raw lumen area, vessel area, and plaque burden. Ones of the key frames can be re-identified based on manipulation of other ones of the key frames.

Abstract: The present disclosure provides to generate a 3D visualization of a vessel from intravascular ultrasound (IVUS) images. In particular, the present disclosure provides to reduce jitter between frames of an IVUS recording to provide a smoother appearance of a longitudinal view of the vessel from the IVUS image frames and to construct a 3D visualization of the vessel from the jitter compensated IVUS image frames.

Abstract: The present disclosure provides a graphical user interface (GUI) arranged to convey information related to the IVUS images and lesion assessment and provide for the user to manipulate the information. The GUIs can be generated to include a cross-section view without assessments post recording of IVUS images and to depict assessments after navigation through frames of the IVUS images.

Abstract: The disclosure provides methods and systems for medical imaging devices to route a path of a vessel on an extravascular image based on at least two points indicated on the image. An image speed map can be generated from the extravascular image and a list of the shortest path from points on the image to a selected point on the image can be identified from the image speed map. Then the path from another point on the image to the selected point on the image identified based on the identified shortest paths.

Abstract: The present disclosure provides to co-register intravascular images of a vessel with one or more extravascular images of the vessel in real-time, such as, during acquisition of the extravascular images. Key points in a first frame of the extravascular images can be identified and then tracked across other frames of the extravascular images. The intravascular images can be co-registered to a frame (or frames) of the extravascular images based on the locations of the key points in the frame.

Abstract: Embodiments herein relate to intravascular imaging display systems and related methods. In an embodiment, an intravascular imaging display system is included having a control circuit and a video output circuit. The video output circuit can be configured to generate a display output including a user interface. The user interface can include graphical elements related to a vessel being imaged. The graphical elements can include a first detected feature portion at least partially defined by a first graphic indicator and a second detected feature portion at least partially defined by a second graphic indicator. The first graphic indicator can be visually distinct from the second graphic indicator. The first detected feature portion and the second detected feature portion can be assigned to represent one or more locations along a vessel wall by the control circuit based on a degree of attenuation of an ultrasound return signal crossing a threshold value.

Abstract: Systems and methods for automatic lesion assessment and/or processing imaging data are disclosed. An example intravascular imaging system may include a catheter including an imaging device. A processor may be coupled to the catheter. The processor may be configured to process imaging data received from the imaging device. The processor may be configured to generate a longitudinal section view of a blood vessel from the imaging data received from the imaging device. The processor may be configured to identify a minimum lumen area along the longitudinal section view of the blood vessel, a distal reference point, and a proximal reference. A display unit may be coupled to the processor. The display unit may be configured to show a display including the longitudinal section view of the blood vessel.
