Patent

CA 2601787

The invention relates to intraoral radiological dental imaging sensors which are placed in the mouth of a patient, while an X-ray source is positioned outside the patient's cheek such as to emit X-rays in the direction of the sensor. According to the invention, the sensor comprises a light source (54) which is modulated by collected radiological imaging information in order to transmit said information optically. Preferably, the light source placed inside the patient's mouth is positioned facing an optical fibre (56) which extends from the mouth. In addition, a light diffuser (60) is placed at the end of the fibre for non-directional emission. A receiver collects the information and transmits same to an image-processing device, specifically in order for the image to be stored.

L'invention concerne les capteurs d'image dentaire radiologiques intra-oraux, c'est-à-dire placés dans la bouche d'un patient, une source de rayons X étant placée à l'extérieur de la joue du patient pour émettre des rayons X dans la direction du capteur.Selon l'invention, le capteur comporte une source de lumière (54) qui est modulée par les informations d'image radiologiques recueillies, pour transmettre par voie optique les informations. De préférence, la source de lumière, placée à l'intérieur de la bouche du patient, est placée en regard d'une fibre optique (56) qui sort de la bouche. Un diffuseur de lumière (60) placé à l'extrémité de la fibre permet d'émettre de manière non directive. Un récepteur recueille les informations et les transmet à un dispositif de traitement d'image, notamment en vue de stocker l'image.
