For radiation safety, a fluoroscope has an adjustable X-ray source-to-intensifier distance (SID) and an X-ray transparent spacer positioned between the source and receptor. As a distance between the source and the intensifier is changed, the spacer is moved or a different sized transparent spacer is used, to ensure a safe minimum skin-to-source distance (SSD) is maintained. A processor is programmed to inhibit the generation of X-rays if the SID is greater than a defined distance and the spacer is not in position.

An X-ray inspection device is configured to prevent water from flowing into areas of the X-ray inspection device during a washing operation. The X-ray inspection device is provided with an X-ray emitter, a cooler, a cooler cover, and an opening/closing member. The cooler cools the X-ray emitter. The cooler cover covers the cooler. Openings are formed in the cooler cover and, when open, provide interior-exterior air flow communication when the cooler is cooling the X-ray inspection device. An opening/closing member is configured for movement between an open orientation opening the opening and a closed orientation closing the openings formed in the cooler cover.

The X-ray emitting unit (100) comprises a box-shaped container (110) with a chamber inside it, and an X-ray tube located in the chamber; the box-shaped container (110) is provided with an opening (111) for X-rays and a plurality of openings for cooling and electrically insulating liquid; having: a first main opening (112A) for the inlet of cooling and electrically insulating liquid, a second main opening for the outlet of cooling and electrically insulating liquid; furthermore, the box-shaped container (110) has: at least one secondary opening (114A) of the first type for cooling and electrically insulating liquid and/or at least one secondary opening (116A, 116B) of the second type for cooling and electrically insulating liquid.

The present disclosure provides an x-ray device including a housing configured to provide a vacuum therein, a cathode arranged inside the housing and configured to emit electrons, an anode arranged inside the housing and configured to produce x-ray radiation when impacted by electrons emitted by the cathode, and a converter configured to convert the x-ray radiation produced by the anode into monochromatic x-ray radiation, wherein the anode is configured to produce x-ray radiation in transmission and is arranged between the cathode and the converter. The present disclosure may be used in medical imaging, therapy, spectroscopy, and the like. Geometries and configurations may be improved compared to previously known x-ray devices when it comes to requirements for space, materials used, complexity of electrical wiring, distance between cathode and anode, and providing supplementary functions.
