Versatile, multimode radiographic systems and methods utilize portable energy emitters and radiation-tracking detectors. The x-ray emitter may include a digital camera and, optionally, a thermal imaging camera to provide for fluoroscopic, digital, and infrared thermal imagery of a patient for the purpose of aiding diagnostic, surgical, and non-surgical interventions. The emitter may cooperative with an inventive x-ray capture stage that automatically pivots, orients and aligns itself with the emitter to maximize exposure quality and safety. The combined system uses less power, corrects for any skew or perspective in the emission, allows the subject to remain in place, and allows the surgeon's workflow to continue uninterrupted.

Provided is a radiation irradiation device that can improve the degree of freedom of an arm part and can reduce the number of noise suppression components, such as a ferrite core. A radiation irradiation device includes a radiation generating part having a radiation source that generates radiation; an arm part having the radiation generating part attached to one end thereof; and a main body part having the other end of the arm part connected thereto. The main body part has a power source part including a three-phase inverter circuit. The power source part supplies a three-phase alternating current voltage to the radiation generating part via the arm part.

An x-ray tube unit includes an x-ray tube unit housing, in which a vacuum housing is disposed, which includes a high-voltage component. The vacuum housing includes an insulating medium circulating in the x-ray tube unit housing flowing around it. Further, a cathode module and an anode are disposed in the vacuum housing, the cathode module lying at high voltage and including an emitter which emits electrons when heating current is fed to it. In addition, a potential difference is present between the cathode module and the anode for accelerating the emitted electrons. In accordance with an embodiment of the invention a high-voltage feed, a heating transformer and a radiation protection component are integrated into the high-voltage component, the high-voltage component being filled at least partly with an electrically-insulating encapsulation material. This produces a compact and installation-friendly x-ray tube unit which has high operational safety.

A shield around an x-ray tube, a voltage multiplier, or both can improve the manufacturing process by allowing testing earlier in the process and by providing a holder for liquid potting material. The shield can also improve voltage standoff. A shielded x-ray tube can be electrically coupled to a shielded power supply.

A radiation generator may include an elongate generator housing having a proximal end and a distal end, a target electrode within the housing at the distal end thereof, a charged particle source within the housing at the proximal end thereof to direct charged particles at the target based upon a first biasing potential, and a field shaping electrode within the housing and adjacent the source to shape a field within the housing. At least one accelerator electrode may be within the housing on an opposite side of the field shaping electrode from the source to accelerate charged particles from the source to the target based upon a second biasing potential different than the first biasing potential. The field shaping electrode may be electrically floating so that the charged particles are directed from the source to the target without applying a biasing potential to the field shaping electrode.

Provided is an X-ray inspection apparatus including: an X-ray tube configured to generate X-rays; a high-voltage power source configured to supply a tube voltage to the X-ray tube to generate X-rays; an X-ray irradiation control section configured to output a first control signal and a second control signal to the high-voltage power source to control the high-voltage power source; and a determination section configured to count at least one of the first control signal and the second control signal output from the X-ray irradiation control section to the high-voltage power source, compare a counted count value with a preset threshold value, and determine a deterioration state of a component constituting the X-ray tube.

Systems, methods, and devices with improved electrode configuration for downhole nuclear radiation generators are provided. For example, one embodiment of a nuclear radiation generator capable of downhole operation may include a charged particle source, a target material, and an acceleration column between the charged particle source and the target material. The acceleration column may include an intermediate electrode that remains floating at a variable potential, being electrically isolated from the rest of the acceleration column.
