Claim One:
1. An odontological X-ray imaging apparatus arranged to enable at least computed tomography imaging, the apparatus comprising: an imaging station in which a selectively placed a subject being imaged by the apparatus; a radiation source and a collimator structure which output x-ray radiation in a shape of a cone beam in a direction of the imaging station; an imaging sensor including a two dimension array of x-ray detecting elements, said imaging sensor being arranged across the imaging station from the radiation source; a construction including an actuator operative to rotate the radiation source and the imaging sensor about the imaging station, at least during an imaging exposure in which x-ray radiation is output from the radiation source and detected by the imaging sensor; and a control system for controlling operation of at least one of the actuator, the radiation source and the imaging sensor, according to at least one of two operative imaging modes, including a first imaging mode for imaging a subject's actual odontological anatomy and a second imaging mode for imaging a physical representation of a subject's odontological anatomy; wherein when operating in the second imaging mode, the control system controls operation of said actuator during an imaging exposure so that said radiation source and said imaging sensor are rotated about the imaging station at an angular velocity of less than approximately 4 degrees/second.
