US 9,795,022 B2 · X-ray imaging system with cabling precharging module

Abstract

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.

Dependent claims

A generator comprising:

a dosing module configured to (i) generate a dosing voltage, and (ii) supply the dosing voltage, via a first conductive element, to an x-ray tube to cause the x-ray tube to emit x-rays, wherein a capacitance exists between the first conductive element and a second conductive element;
and
a precharge module configured to (i) generate a precharge voltage, and (ii), supply the precharge voltage to a third conductive element to reduce the capacitance between the first conductive element and the second conductive element,
wherein (i) the precharge voltage is equal to the dosing voltage, or (ii) the precharge module is configured to supply the precharge voltage to the third conductive element prior to the dosing module supplying the dosing voltage to the first conductive element.
