A quantitative coronary artery analysis system (30) is described which includes a determination (40) of the set of most likely data points representing the edge of an artery to enable an analysis program to calculate the dimensional information (46) of interest for a patient from an x-ray image of the selected artery wherein the program includes the steps of performing an axi-linear transform (38) of the image data with subsequent filtering, rejection and correction of selected data points (42) such that the user is provided with the calculated dimensional data (46) for an artery, other blood vessel, or organ of a patient.

La présente invention a pour objet un système d'analyse quantitative de l'artère coronaire (30) qui consiste à déterminer (40) l'ensemble de points de données les plus probables représentant le bord d'une artère, afin de permettre à un programme d'analyse de calculer à partir d'une image radiologique de l'artère sélectionnée l'information dimensionnelle (46) concernant un patient donné. Le programme consiste à effectuer une transformation linéaire et axiale (38) des données de l'image, suivie du filtrage, du rejet et de la correction de points de données sélectionnés (42), dans le but de fournir à l'usager les données dimensionnelles calculées (46) concernant une artère, un autre vaisseau sanguin, ou un organe appartenant à un patient donné.
