Abstract
A system for capturing multiple intraoral images includes an intraoral sensor. The sensor includes a sensor array, a transmitter and a power source that provides power to the sensor array and the transmitter. The sensor is configured to be inserted inside a patient'"'"'s oral cavity, capture an image upon the presence of incident radiation and transmit from within the oral cavity via a wireless link electrical signals representing the image. A base station positioned outside the oral cavity is configured to receive the electrical signals transmitted from the sensor. The sensor is capable of capturing transmitting to the base station electrical signals representing multiple intraoral images without requiring that the sensor be removed from the patient'"'"'s oral cavity.

13. An intraoral sensor, comprising:
-
a radiation sensitive sensor array including 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;
an event detection circuit including a current sensing device, said event detection circuit 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; and
a transmitter adapted to transmit via a wireless link signals representing an image captured by the sensor array. - View Dependent Claims (14, 15, 16, 17, 18)
