PROCÉDÉ, SYSTÈME ET PROGRAMME INFORMATIQUE PERMETTANT DE DÉTERMINER DES DONNÉES DÉFINISSANT UNE ESTIMATION DE L'ÉPAISSEUR ET LA DENSITÉ D'UNE STRUCTURE DE TISSU D'INTÉRÊT À PARTIR DE DONNÉES D'IMAGERIE
The method comprises:modelling measured variations of an imaging parameter along a line crossing a tissue structure of interest of a patient as a function having a thickness parameter, a first density parameter and a blur parameter；determining a thickness-density relationship between tissue structure density and tissue structure thickness from multiple thickness and density measurements made on a reference tissue structure of a subject which is not the patient； andfitting said function to said measured variations while ensuring said first density parameter and thickness parameter follow said thickness-density relationship, to search for optimal values comprising data defining an estimate of the thickness and density of the tissue structure of interest.The system and the computer program implement the method of the invention.
