Abstract

L'objectif de l'invention est de faciliter le marquage d'un film radiologique (7 ; 7.1), pouvant être exposé pour former des images d'examen d'un patient, au moyen de données supplémentaires spécifiques aux patients. A cet effet, un dispositif de marquage (4), intégré dans la structure d'un système d'examen radiologique destiné notamment à une mammographie analogique, est positionné par rapport à un film radiologique (7 ; 7.1) de sorte que le dispositif de marquage (4) soit placé à l'extérieur des rayons X (9) lors de l'examen et permette l'exposition du film radiologique (7; 7.1) lors du marquage. Dans un deuxième mode de réalisation, un élément écran (11) servant à protéger le dispositif de marquage (4) pendant la prise du cliché radiologique est placé sur le côté du film opposé aux rayons X de façon à masquer le dispositif de marquage (4) vis-à-vis des rayons X (9) lors de l'examen.
