Patent ID: 8149990

Claim:
An intra-oral X-ray imaging arrangement, which includes a control system, a radiation source, an electric image data receiving sensor including sensor electronics and a wireless transmission link for transmitting at least image data detected by the sensor to a base station, to an image processing device or to some other device, a transmitter and a receiver of which transmission link being arranged, on the one hand, in connection with the sensor, and on the other hand, at least in functional connection with said base station or some other device the arrangement further including or said transmission link further being arranged to function also as a wireless power transmission link, wherein said power transmission link is structured and arranged to supply the sensor with energy only in connection with an imaging event and only after a procedure of positioning the image data receiving sensor for an exposure as part of the imaging event is initiated and wherein the sensor either includes no components capable of storing energy, or the total energy storing capacity of all components together included in the sensor electronics is lower than the energy required by the sensor in connection with an individual imaging event.
