Method for controlling a radiological apparatus through the use of: a) a control unit adapted to activate X-ray emission from an X-ray emitter of the radiological apparatus at the beginning of an exposure and deactivating X-ray emission from said X-ray emitter subsequently, and b) an X-ray transducer associated with an image detector of the radiological apparatus; wherein said control unit repeatedly determines, simultaneously or with a different frequency, a first and a second predicted values of total X-ray dose based on a signal received from said X-ray transducer, and wherein said control unit deactivates the X-ray emission based on at least said first and second predicted values; wherein in order to determine said first and second predicted values, said control unit repeatedly performs total X-ray dose estimates according to a model, wherein one or more parameters of said model are determined and modified during operation of the radiological apparatus; wherein said first predicted value is calculated at a time "t" and corresponds to an expected value at a subsequent time "t+dt" of total X-ray dose absorbed by said X-ray transducer starting from the beginning of said exposure, and wherein said control unit makes a comparison between said first predicted value and a predetermined value and deactivates X-ray emission if said comparison indicates that said first predicted value is greater than or equal to said predetermined value; wherein said second predicted value is calculated at a time "t" and corresponds to an expected value at a predetermined subsequent time "tm" of total X-ray dose absorbed by said X-ray transducer starting from the beginning of said exposure, and wherein said control unit makes a comparison between said second predicted value and a predetermined value and deactivates X-ray emission if said comparison indicates that said second predicted value is lower to said predetermined value; wherein the predetermined subsequent time "tm" is a maximum exposure time. a) a control unit adapted to activate X-ray emission from an X-ray emitter of the radiological apparatus at the beginning of an exposure and deactivating X-ray emission from said X-ray emitter subsequently, and b) an X-ray transducer associated with an image detector of the radiological apparatus;
