ABSTRACT:
An intraoral sensor includes a radiation sensitive sensor array, an event detection circuit, and a transmitter. The radiation sensitive sensor array includes a scintillator which converts x-rays into visible light radiation, and a plurality of pixels sensitive to visible light radiation to capture an image upon the presence of incident radiation. The event detection circuit includes a current sensing device and is configured to generate a triggering signal indicating the presence of radiation incident on the sensor array based upon the amount of electrical current drawn by the sensor array. The transmitter is adapted to transmit via a wireless link signals representing an image captured by the sensor array.
