The objective of the procedure is the operation of an X-ray device that provides maximum power at all times, and for this the supply or input voltage to the X-ray tube must be half of the source voltage ((Vbat) / 2 or (Line) / 2), and what we will call reference voltage (Vref), the procedure is that if a change in the reference voltage occurs, a modification of the supplied current occurs, modifying the exposure time, so that the power delivered at all times is maximum. In short, it is based on a procedure that regulates the current of the tube according to the supply voltage (of the batteries or the network).
