Abstract
The invention relates to intraoral radiological dental image sensors, i.e. ones placed in a patient's mouth, an X-ray source being placed outside the patient's cheek in order to emit X-rays in the direction of the sensor. According to the invention, the sensor comprises a light source which is modulated by the collected radiological image information, in order to transmit the information optically. The light source, placed inside the patient's mouth, is preferably placed facing an optical fiber which emerges from the mouth. A light diffuser, placed at the end of the fiber, makes it possible to emit nondirectionally. A receiver collects the information and transmits it to an image processing device, in particular with a view to storing the image.
