摘要
The method is used to control a radiological apparatus (100) through a) a control unit (130) adapted to activate the emission of X-rays by an X-ray emitter (110) of the radiological apparatus at the beginning of an exposure and to deactivate the emission of X-rays by said X-ray emitter (110) subsequently, and b) an X-ray transducer (140) associated with an image detector (120) of the radiological apparatus; the control unit (130) repeatedly determines, preferably with a predetermined period "dt", a predicted value of total X-ray dose based on a signal received from said X-ray transducer (140), and deactivates the emission of X-rays based at least on said predicted value; in order to determine the predicted value, the control unit (130) repeatedly performs estimates of the total X-ray dose according to a model; one or more parameters of the model are determined and modified during the operation of the radiological apparatus (100).
