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.
