    Abstract: The disclosure relates, in part, to computer-based visualization of stent position within a blood vessel. A stent can be visualized using intravascular data and subsequently displayed as stent struts or portions of a stent as a part of a one or more graphic user interface(s) (GUI). In one embodiment, the method includes steps to distinguish stented region(s) from background noise using an amalgamation of angular stent strut information for a given neighborhood of frames. The GUI can include views of a blood vessel generated using distance measurements and demarcating the actual stented region(s), which provides visualization of the stented region. The disclosure also relates to display of intravascular diagnostic information such as indicators. An indicator can be generated and displayed with images generated using an intravascular data collection system. The indicators can include one or more viewable graphical elements suitable for indicating diagnostic information such as stent information.

    Abstract: Aspects of the disclosure relate to the identification of when a blood vessel has been sufficiently cleared of blood so as to capture intravascular images of the vessel wall. The disclosed systems and methods allow for the identification of an initial and a final blood clearing based on the identification of edges within scanlines of a plurality of image frames. The edges of a plurality of scanlines may be analyzed to determine an average edge offset for each image frame, and the average edge offsets for a plurality of image frames may be averaged over various time-windows, so as to determine when the initial and final blood clearing events have occurred. Once a final blood clearing event has been identified, the disclosed system may automatically initiate a catheter pullback procedure, so as to capture intravascular images over a length of the vessel that has been sufficiently cleared of blood.
