1. A method for displaying vascular parameter data, the method comprising:
receiving, in a processor, at least a first and a second 2-D angiographic image each comprising (i) respective 2-D frames of reference, and (ii) vascular image contents viewed from angles at least 30° different from each other;
creating, via the processor, a model including a data structure configured to link a plurality of 2-D locations in each of the first and the second 2-D angiographic images;
determining, via the processor, the vascular parameter data for the linked plurality of 2-D locations using at least one of the first 2-D angiographic image and the second 2-D angiographic image;
forming visual elements of the vascular parameter data at the linked plurality of 2-D locations in the frame of reference of the first 2-D angiographic image; and
displaying via the processor, the visual elements of the vascular parameter data at the plurality of linked 2-D locations in the frame of reference of the first 2-D angiographic image and overlaid on the first 2-D angiographic image,
wherein the display of the vascular parameter data at each of the linked 2-D locations is based on a plurality of accessed parameter data elements, and
wherein the same or a different data structure links at least a third 2-D angiographic image not registrable to consistently align with the first and second 2-D angiographic images by an invertible 2-D geometrical transform, where at least some values of the accessed parameter data elements are derived from processing of a plurality of linked 2-D locations of the third 2-D angiographic image.
