An X-ray source includes an X-ray tube; a radiation shielding shell enclosing the X-ray tube, the radiation shielding shell including a collimator formed integrally with it, wherein the radiation shielding shell comprises finely dispersed powder, polyester or epoxy resin and hardener; a cooler system providing oil to the X-ray tube; and an oil filled tank supplying the oil to the cooler system. There is a central shielding element shaped as a cylinder inside the radiation shielding shell and one or more end shielding elements around the X-ray tube. The central and end shielding elements are made of lead.

An X-ray generating apparatus comprises a storage housing, an insulating housing arranged in the storage housing, an X-ray generating tube arranged at least partly in the insulating housing, and a plurality of electrical components arranged in the insulating housing. In the X-ray generating apparatus, the plurality of electrical components include a mold transformer, the mold transformer includes a core, an insulator covering the core, and a heat-dissipating path configured to move heat from the core to an external space of the insulator, and the heat-dissipating path includes a hole provided in the insulator to extend from the external space toward the core.

A passive, uninterrupted cooling system continues to absorb waste heat generated with a diagnostic medical imaging system during a patient scan, in the event of a power failure incident or disruption of cooling water supply within an imaging facility. The passive, uninterrupted cooling system incorporates one or more phase change materials (PCMs) that maintain the cooling system temperature at material's melting temperature, while absorbing the imaging system's waste heat. This enables clinicians to complete an in-progress imaging scan of a patient within the scanning system's operational temperature specifications. In some embodiments, the PCMs absorb transient heat spikes generated during patient scans, in order to maintain a relatively consistent cooling system operational temperature. In some embodiments, the passive, uninterrupted cooling system is used to cool PET/CT, PET, or CT imaging systems.

A method for controlling a temperature of an X-ray device, comprises: acquiring planning information, including at least one operating parameter of at least one component of the X-ray device, for a planned operation of the X-ray device; identifying a planning temperature of the at least one component of the X-ray device based on the at least one operating parameter; operating the X-ray device in accordance with the planning information; and controlling a temperature control unit of the X-ray device prior to and/or during operation of the X-ray device based on the planning temperature such that the temperature control unit controls a temperature of the at least one component of the X-ray device to a defined temperature or a defined temperature range by providing a heating capacity and/or a cooling capacity.

An X-ray tube housing is disclosed that has oil channels integrated (e.g., built into) the X-ray tube housing that accommodate a flow of oil through interior spaces of the X-ray tube housing. A first oil channel from a mid-casing portion of the X-ray tube housing to a pump housing inlet is built into the mid-casing portion, and a second oil channel from a pump housing outlet to a heat exchanger located in an anode-side casing is built into the anode-side casing. The integrated oil channels reduce a number of sealing joints, which reduces the opportunities for leaks, and allows an X-ray tube assembly to be assembled with fewer parts.

Systems and methods for a power electronics assembly. The power electronics assembly includes, in one example, a gate board electronically connected to a power board, a plurality of power modules which each include multiple power terminals which are electronically connected to the power board via multiple attachment devices, and multiple interconnection boards. In the power electronics assembly, each of the plurality of interconnection boards are electronically connected to the gate board via multiple gate board terminals and one of the power modules via multiple control terminals.

A smart power system and method to protect an X-ray tube of a CT imaging system during a power outage, the system and method comprising monitoring a remining amount of power from a backup power source supplied by an UPS coupled to a PDU that is providing power to the CT imaging system. The X-ray tube having a liquid metal bearing rotating assembly. The system and method automatically strategizing and determining where to supply the remaining amount of backup power to prevent a hot landing of the X-ray tube liquid metal bearing rotating assembly.

Methods and systems are provided for preventing hot landings of a motor of an X-ray imaging system in the event of a power loss. In an example, a method for an X-ray tube of an imaging system includes, during a scan of a subject with the imaging system, supplying energy from a main power supply to the X-ray tube in order to rotate a target of the X-ray tube, selectively recovering energy from the X-ray tube and storing the recovered energy in an energy storage circuit of the imaging system, and detecting a loss of the main power supply, and in response, supplying energy from the energy storage circuit to the X-ray tube in order to rotate the target at a threshold speed.

One or more example embodiments relates to a method for controlling the temperature of an X-ray device, comprising detecting a heating parameter of a heating element, identifying a target heating parameter for the heating element, and adjusting a fluid supply parameter of a fluid supply unit as a function of a comparison of the heating parameter and the target heating parameter.
