(57) A circuit that aims to control the exposure of Xrays by means of an intermediate or feedback current which is directly proportional to the grid current (IG), which in turn controls the current of the anode of the tube and which is ultimately responsible for the emission of the X-ray photons, comprising an anode (A), a cathode (K) connected to ground, as well as a grid (G) connected to a grid current controller circuit (IG) comprising a DC-DC converter (CONV) or "buck converter" to which a power supply voltage (Vsup) is connected, the output of which is connected to an inverter (INV) that is in turn connected to a transformer (TR), where the output of this transformer (TR) is connected to a rectifier (RECT) whose outputs are connected to the grid (G) and to ground. In addition, in said controller circuit there is a control circuit (CONT).
