Title (EN) METHOD TO RADIOGRAPHICALLY DETERMINE GEOMETRICAL PARAMETERS AND/OR SUBSTANCE STATE OF AN OBJECT UNDER STUDY
(FR) PROCÉDÉ DE DÉTERMINATION RADIOGRAPHIQUE DE PARAMÈTRES GÉOMÉTRIQUES ET/OU D'ÉTAT DE SUBSTANCE D'UN OBJET À L'ÉTUDE
Abstract:
(EN) The present invention relates to a method to determine geometrical parameters of an object under study by means radiography, the object can be described geometrically, wherein intercepts that go through the material of the object under study can be determined from a projection of the object - e.g. a tube - imaged by an X- or gamma-radiation source if exposition data of the radiographic image are available. These intercepts that go through the material of the object - i.e. the intercept curves - allow that the object under study - e.g. the tube - have a dimension that is larger than the dimension of the device (film/detector) used to take the radiographic image. During the course of said method, the source of radiation, the object under study and the device (film/detector) used to take the radiographic image are in a fixed position.
(FR) La présente invention concerne un procédé de détermination de paramètres géométriques d'un objet à l'étude par radiographie, l'objet pouvant être décrit géométriquement, des segments d'interception qui traversent le matériau de l'objet à l'étude pouvant être déterminés à partir d'une projection de l'objet, par exemple un tube, mis en image par une source de rayons X ou de rayons gamma si des données d'exposition de l'image radiographique sont disponibles. Ces segments d'interception qui traversent le matériau de l'objet, c'est-à-dire les courbes d'interception, permettent à l'objet à l'étude, par exemple le tube, de présenter une dimension plus grande que la dimension du dispositif (film/détecteur) utilisé pour prendre l'image radiographique. Pendant le déroulement dudit procédé, la source de rayonnement, l'objet à l'étude et le dispositif (film/détecteur) utilisés pour prendre l'image radiographique se trouvent dans une position fixe.
