The invention relates to an RX stereoradiography device comprising a horizontal rotating plate (13) which is optionally translational, characterized in that said plate (13) can be oriented according to two angular positions at 90·, each of which in order to take two photos which are orthogonal in relation to the other, also characterized in that the device also comprises a frame (14) which is joined to the horizontal plate (13) and, optionally, an additional maintenance device (15) for receiving the subject and at least three markers (16) made of a radio-opaque material disposed in a connected manner on the frame (14), one of said markers (1) being identified as the origin of an orthogonal, three-dimensional point of reference and the other markers (16) being disposed in such a way that it is possible to provide, by projection, knowledge of at least one distance value between the markers (16) according to the three axes X, Y and Z of said point of reference, respectively Lx, Ly and H. The invention also relates to the applications, implementation and use thereof.
La présente invention concerne un dispositif de stéréoradiographie en RX avec un plateau horizontal (13) rotatif et éventuellement translatif caractérisé en ce que le plateau (13) est orientable selon deux positions angulaires à 90~ l'une de l'autre pour le tirage de deux clichés orthogonaux l'un par rapport à l'autre et en ce que le dispositif comprend aussi une armature (14) solidaire du plateau horizontal (13) et éventuellement un dispositif complémentaire de maintien (15) destiné à acceuillir le sujet et au moins trois marqueurs (16) en matériau radio opaque disposés solidairement sur l'amarture (14), l'un des marqueurs (1) étant identifié comme origine d'un repère tridimensionnel orthogonal, les autres marqueurs (16) étant disposés de manière à fournir par projection la connaisance d'au moins une valeur de distance entre les marqueurs (16) selon les trois axes X, Y et Z dudit repère, respectivement Lx, Ly et H. L'invention concerne également les applications, mises en .oelig.uvre et utilisation du dispositif.
