Patent ID: 11226296

Abstract:
A tunnel computerised tomographic scanner comprising a rotor (3), an X-ray emitter (7) mounted on the rotor (3), an X-ray detector (8) mounted on the rotor (3), on the opposite side of a detecting zone (4), the X-ray detector (8) comprising a scintillator (9) which has at least one emission face (10) from which the scintillator (9) emits light in the visible spectrum when it is struck by X-rays, and a plurality of video cameras (12) which are positioned in such a way that each of them frames at least one portion of the scintillator (9), for acquiring one after another second images, in the visible spectrum, of the respective portion of the scintillator (9), wherein, according to the method, at least two separate video cameras (12) substantially frame each zone of the emission face (10), and an electronic processing unit is programmed to combine all of the second images obtained by the video cameras (12) and to obtain a first image of the emission face (10), to be used for the tomographic reconstruction of an object (6) which is placed in the detecting zone (4).
