Non-invasive methods for detecting arterial disease in vivoinclude obtaining acoustic signals from a sensor held on an external body region proximate an artery. A complex frequency grid of frequencies and associated lifetimes of the obtained acoustic signals is generated. A predictive model of complex frequencies associated with peak-perturbation acoustic signals attributed to boundary perturbations in vivo that occur with early stage arterial disease is provided. A predictive model of complex frequencies associated with line- perturbation acoustic signals attributed to boundary perturbations in vivo that occur with later stage arterial disease and thickening of arterial junctions is also provided. It is determined whether peak and/or line- perturbation acoustic signals of the predictive models are present to detect whether the subject has arterial disease.

L'invention concerne des procédés non vulnérants permettant de détecter une maladie artérielle <i>in vivo </i>, et qui comprennent les étapes consistant à : obtenir des signaux acoustiques provenant d'un détecteur maintenu sur une région corporelle externe, à proximité d'une artère ; produire une grille de fréquences complexes, qui contient les fréquences et les durées de vie associées des signaux acoustiques obtenus ; produire un modèle prédictif des fréquences complexes associées aux signaux acoustiques de perturbation de pic, lesquels sont attribués aux perturbations limites <i>in vivo </i> qui apparaissent à un stade précoce d'une maladie artérielle ; produire aussi un modèle prédictif des fréquences complexes associées aux signaux acoustiques de perturbation linéaire, lesquels sont attribués aux perturbations limites <i>in vivo </i> apparaissant à un stade ultérieur d'une maladie artérielle et/ou à l'épaississement de branches artérielles ; déterminer la présence de signaux acoustiques de perturbation de pic et/ou linéaire des modèles prédictifs afin de détecter si le sujet est atteint d'une maladie artérielle.
