Abstract: The invention concerns a device for identification of a detector unit in an X-ray imaging apparatus. For this purpose there is a detector unit (1a or 1b or 1c . . . ), selected from a group (10) of different detector array units (1a, 1b, 1c . . . ), and a transmitter-receiver (8) at side(s) of a space (V) for said object or a rack for storing those detector units belonging to said group. Recognition means (11) or a sensor units capable of detecting presence and absence of the detector units is also provided, as well as a communication line (2) for providing identification data concerning the presence (P2) or absence of a single detector unit in a predetermined volume or place.

Abstract: A method for X-ray imaging of mouth with intra oral imaging, method comprising: placing at least one image sensor inside the mouth, radiating from outside of the mouth with X-ray source, receiving X-ray radiation to form at least two sets of image information representing at least two different spectrums of X-ray absorption to achieve a optimal image information for analysis.

Abstract: The invention relates to a method for performing X-ray imaging in intraoral application. The method comprises irradiation of an object with a substantially low amount of X-radiation, and a substantially low amount of X-radiation passed through the object is received. The method comprises compiling a sample of image data from the received, substantially low amount of X-radiation. The sample of image data information is communicated to an X-ray source (100), and according to the sample of image data information the object is irradiated with X-radiation, from which X-radiation the part that has passed through the object is received, and the received X-radiation, which is consistent with the sample of image data information, is used for compiling image information.
