Predictive method for controlling a radiological apparatus and radiological apparatus implementing it

A method for controlling a radiological apparatus through the use of:

• a) a control unit configured 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, a predicted value 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 predicted value;
• wherein in order to determine said predicted value, 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 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 predicted value and a predetermined value and deactivates X-ray emission if said comparison indicates that said predicted value is lower to said predetermined value;
• wherein the predetermined subsequent time “tm” is a maximum exposure time according to legislation.
