Abstract: In a computed tomography scanner having an emitter for emitting a beam of given radiation through an object to be analysed, a detector for receiving said beam after the beam itself has traversed the object, and a rotating arm, which supports the emitter and the detector and rotates the emitter and the detector about the object along a series of angular positions, there is generated a succession of first pulses, each of which activates the detector in one respective angular position, and a succession of second pulses for activating the emitter so that it will emit a dose of radiation in each angular position, associated to which is a respective dose of radiation in such a way as to pre-define a distribution of doses of radiation along the series of angular positions.

Abstract: In a computed tomography scanner provided with an emitter for emitting a beam of radiation through an object to be analyzed and a detector for acquiring radiographies of the object, the detector generates a synchronization signal corresponding to its state of activation for acquiring the radiographies, and the emitter is controlled via the synchronization signal in such a way that the beam of radiation will be emitted when the detector is already activated.

Abstract: A cheek and lip retractor is defined by a supporting member supporting a pair of retracting elements to be inserted at least partially in a patient's mouth, with a light source housed in the supporting member. An optical device for the transmission of the light emitted from the light source inside the mouth extends along the supporting member and/or along the retracting elements.

Abstract: A unit for acquiring dental radiographic images of a patient is provided with an x-ray head coupled to a respective supporting arm via a ball joint.

Abstract: In a computed tomography scanner, the panoramic image of an object to be analysed is reconstructed by: acquiring volumetric tomographic data of the object; extracting, from the volumetric tomographic data, tomographic data corresponding to at least three sections of the object identified by respective mutually parallel planes; determining, on each section extracted, a respective trajectory that a profile of the object follows in an area corresponding to said section; determining a first surface transverse to said planes such as to comprise the trajectories; and generating the panoramic image on the basis of a part of the volumetric tomographic data identified as a function of said surface.

Abstract: A cheek and lip retractor is defined by a supporting member (4) supporting a pair of retracting elements (2) to be inserted at least partially in a patient's mouth (3), by a light source (11) fixed to the supporting member (4), and by an optical device (17) for the transmission of the light emitted from the light source (11) inside the mouth (3); the optical device (17) extending wholly along the supporting member (4) and/or the retracting elements (2).
