La présente invention concerne un dispositif de photographie à rayons X capable d'ajuster un angle d'émission de rayons X d'une unité de source de rayons X par la forme d'une image optique affichée sur la surface du visage d'une personne examinée et, en particulier, capable d'aligner facilement des angles de l'unité de source de rayons X et d'un capteur en permettant à une direction d'émission de rayons X et à la surface du visage de la personne examinée d'être disposées perpendiculairement par l'intermédiaire de l'ajustement. À cet effet, le dispositif de photographie à rayons X de la présente invention comprend : l'unité de source de rayons X pour émettre un rayon X au niveau d'un capteur de rayons X positionné dans la cavité buccale de la personne examinée; une unité d'émission de lumière pour générer l'image optique en émettant une lumière d'identification sur la surface du visage de la personne examinée, la surface correspondant à une partie au niveau de laquelle le rayon X est émis par l'unité de source de rayons X, de telle sorte que l'unité d'émission de lumière permet à un état d'alignement du capteur de rayons X et de l'unité de source de rayons X d'être identifié sur la base d'un degré de distorsion de l'image optique par rapport à une forme transversale de la lumière d'identification.
