Abstract:
1. An intraoral dental radiological system comprising a radiological image sensor adapted for being inserted into a patient's mouth, the sensor comprising an image sensor array providing electronic signals representing a radiological image, an electrical cable having a first end connected to the radiological image sensor and a second end located outside of the mouth when the image sensor is in the mouth, the second end having a light source that is digitally modulated as a function of electrical information coming from the sensor, and a light receiver located at a distance from the patient for detecting a modulation of the light emitted by the source and transmitting a signal corresponding to the modulation to a device for exploiting the signal, wherein the light source comprises at least four light-emitting diodes which receive the modulation produced by the sensor in parallel and which have different physical orientations so as to emit in a wide range of directions.
