1. A method, comprising:
receiving, by one or more processors, vessel data including image data for a vessel;
determining, by the one or more processors based on the vessel data, a plurality of vessel diameter values for at least a portion of the vessel;
determining, by the one or more processors based on the vessel data, a minimum lumen area (MLA) from a set of area values calculated at positions along at least the portion of the vessel;
providing for output, by the one or more processors, a first panel comprising a first axis, a second axis and a two-dimensional representation of at least the portion of the vessel,
wherein the first axis corresponds to at least one of the plurality of determined vessel diameter values and the second axis corresponds to a positions along at least the portion of the vessel;
providing for output, by the one or more processors, a vessel diameter value of the plurality of determined vessel diameter values for a user selected frame relative to the two-dimensional representation of at least the portion of the vessel; and
providing for output, by the one or more processors, the MLA relative to at least the portion of the vessel to guide stent planning or stenosis assessment.
