Abstract

La présente invention porte sur un dispositif de photographie à rayons X qui peut photographier rapidement en changeant différents modes de photographie tels qu'un mode debout, un mode de table et autre, avec un seul dispositif de photographie à rayons X. A cette fin, le dispositif de photographie à rayons X selon la présente invention comporte : un cadre de base ; un cadre de support, couplé de manière pivotante à un côté du cadre de base par l'intermédiaire d'un axe de charnière et sur un côté duquel un détecteur de rayons X, destiné à détecter des rayons X irradiés depuis un dispositif de génération de rayons X, est agencé de manière coulissante ; un actionneur, dont une extrémité est fixée rotative au cadre de base et dont l'autre extrémité est fixée rotative au cadre de support espacé à une distance prédéterminée de l'axe de charnière, et qui fait pivoter le cadre de support autour de l'axe de charnière dans une plage angulaire prédéterminée tout en déplaçant un axe d'entraînement dans celui-ci vers l'avant et vers l'arrière par pression pneumatique ou hydraulique fournie depuis l'extérieur.
