Abstract:
1. A treatment process of radiological images of a region of interest of a patient, the radiological images being 2D projection images, in which a longilineal tool has previously been inserted into an artery, the process comprising: using a treatment system and a calculation unit, obtaining at least one set of images, the at least one set of images comprising an at least one first image and an at least one second image of the region of interest, the at least one first image being an image of the region of interest into which a contrast product has previously been injected, the at least one second image being an image of the region of interest without a contrast product or with a minimal quantity of contrast product, each of the at least one set of images corresponding to a given angulation, wherein for each set, the process comprises: segmenting the at least one first image to obtain an at least one first segmented image and to detect a plurality of arteries of the region of interest; segmenting the at least one second image to obtain an at least one second segmented image and to detect and isolate the tool; defining in the at least one first segmented image a plurality of lines, wherein each line defines an artery; determining, from the second segmented image and the defined lines, an artery of interest corresponding to the artery in which the tool has been inserted, wherein the defined line of the artery of interest is closest to the tool; and applying a quantitative analysis algorithm of coronary lesions to the artery of interest to detect lesion of the artery of interest.
