In an all electronic multi energy system at least two levels of x-ray energy are produced sequentially and rapidly at independently controllable and different power or flux levels. In the system there are a triode x-ray tube which selects the operating current of the system and a series connected temperature limited diode or triode which controls the voltage across the first x-ray tube. This system provides improved performance in x-ray imaging applications at low cost, for example, in baggage inspection or measurements of bone densities and medical fluoroscopy. The objective of the system is to produce a maximum amount of useful information with a minimum amount of exposure for the patient or object to be illuminated by x-ray flux. With human patients this is desirable for health safety reasons; for baggage inspection, to reduce exposure to photographic films.

Multi energy system for x-ray imaging applications

An optical device for interacting with x-ray radiation, wherein the device includes an optical element configured for use as part of a spectroscopy tube, proportional counter, Geiger counter, optical detector or similar optical instrument. An exposed surface of the optical element is coated with at least one bonded layer of boron hydride composition to protect against abrasion, corrosion and other forms of degradation, as well as to provide enhanced sealing of the Z material against leakage. Methods of bonding the desired coating to the optical element are also disclosed.
