1. A method of processing images of a region of interest of a patient, comprising the steps of: acquiring a reference image of the region of interest of the patient; during a pullback of an intravascular sensor introduced inside the region of interest of the patient, triggering simultaneously the steps of: acquiring a set of non-image data using the intravascular sensor, wherein the non-image data is characteristic of the region of interest, and acquiring a succession of images of the region of interest, each of the succession of images associated with the location of the intravascular sensor when acquiring the non-image data, respectively; registering the succession of images for which the non-image data collected by the intravascular sensor are available; associating the location of the intravascular sensor relative to the step of acquiring the non-image data using the intravascular sensor; and displaying values corresponding to the non-image data collected by the intravascular sensor at positions on the reference image corresponding to the location at which the respective non-image data was collected.
