An X-ray imaging system can include an X-ray tube, an X-ray generator, a precharging module and a triaxial cable. The X-ray tube can be configured to generate an X-ray emission and include an anode, a cathode and a filament. The X-ray generator can be coupled with the X-ray tube and include a high voltage module and a low voltage module. The high voltage module can be being configured to supply a dosing voltage across the X-ray tube and the low voltage module can be configured to supply a dosing current to the filament. The precharging module can be configured to supply a precharge voltage. The triaxial cable can electrically connect the X-ray generator to the X-ray tube. The outer shield conductor of the triaxial cable can carry a ground voltage, the inner shield conductor can carry the precharge voltage and the center conductor can carry the dosing voltage. |
