The invention relates to an intra-oral x-ray imaging arrangement which includes an imaging sensor (30) arranged positionable within a patient's mouth and a control system of the imaging arrangement. The control system is arranged in functional connection with a means that has been arranged to send measurement signals to the control system informing on position of at least one component included in the arrangement. In connection with the imaging sensor (30), and a radiation source (4) included in the arrangement, means (A, M, G) have been arranged to measure their spatial position and to send measurement signals based on these measurements to the control system arranged with a means to determine, based on said measurement signals, information on mutual spatial position of the imaging sensor (30) and the radiation source (4), or of a component (40, 50) arranged to the radiation source (4). |
