In part, the disclosure relates to intravascular data collection systems and the software-based visualization and display of intravascular data relating to detected side branches and side branch obstruction. An estimate of side branch diameter can be made based on a vessel profile or a maximum diameter of a vessel at a distal and proximal location relative to the side branch. A amount of side branch obstruction may be determined by comparing an observed side branch diameter with in the image data with the estimated side branch diameter. In addition, an amount of blood flow obstruction may also be determined.

Intravascular data visualization and interface systems and methods

In part, the disclosure relates to intravascular data collection systems and the software-based visualization and display of intravascular data relating to detected side branches and detected stent struts. Levels of stent malapposition can be defined using a user interface such as a slider, toggle, button, field, or other interface to specify how indicia are displayed relative to detected stent struts. In addition, the disclosure relates to methods to automatically provide a two or three-dimensional visualization suitable for assessing side branch and/or guide wire location during stenting. The method can use one or more a computed side branch location, a branch takeoff angle, one or more stent strut locations, and one or more lumen contours.

In part, the disclosure relates to intravascular data collections and generation of representations thereof include one or more view of regions associated with side branches or arteries such as a carina or bifurcation. In one embodiment, accessing a set of intravascular data stored in machine readable memory; performing side branch detection with regard to the intravascular data to identify one or more side branches; and identifying a plurality of frames for the one or more side branches is performed. An automatic viewing angle that is toggleable is used in one embodiment.
