1. A system for evaluating a vessel of a patient, comprising:
a processor configured to:
receive a first image of the vessel obtained from an imaging device during a first procedure, wherein the first image depicts a same location of the vessel with a first vessel structure;
receive a second image of the vessel obtained from the imaging device during a different, second procedure performed subsequent to the first procedure and subsequent to a therapeutic procedure directed to the same location, wherein the second image depicts the same location with a different, second vessel structure resulting from a physiological change caused by the therapeutic procedure, wherein the therapeutic procedure comprises at least one of percutaneous coronary intervention (PCI), angioplasty, stenting, coronary artery graft, ablation, cryotherapy, atherectomy, or administration of a drug, wherein the first image and the second image comprise a same imaging modality and a same view of the vessel;
positionally align the first image and the second image such that the same location is in the same position in each of the first and second images;
receive a user input selecting the same location in the first image such that the first vessel structure is identified;
identify, based on the user input and the positional alignment of the first and second images, the same location in the second image;
generate a screen display comprising:
the first image;
a first marker overlaid on the first image proximate to the same location such that the same location with the first vessel structure is visually indicated;
the second image displayed simultaneously as the first image and spaced from the first image; and
a second marker overlaid on the second image proximate to the same location such that the same location with the different, second vessel structure resulting from the physiological change caused by the therapeutic procedure is visually indicated in the second image; and
output the screen display on a display.
