<p>An X-ray tube comprises a containment element (2) in which a cathode (4) and an anode (5) are mounted. The anode (5) comprises a first main face (6) which is substantially facing towards the cathode (4) and a second main face (7) which is facing the opposite way to the first face (6). There are also cooling means (8) applied to the second main face (7) of the anode (5) and filter means (10) for filtering, based on respective wavelengths, the X-rays emitted by the anode (5). The cooling means (8) and the filter means (10) both consist of a heat conductor element (9) which is thermally coupled with the second face (7) of the anode (5) and which is equipped with a plurality of inner micro-channels in which, in practice, a pressurised coolant liquid can flow with a turbulent motion. The containment element also comprises an X-ray emission section (3) positioned in such a way that, in practice, it receives the X-rays emitted from the second main face (7) of the anode (5) after they have passed through the filter means (10).</p> |
