WebX-rays are a form of electromagnetic radiation similar to radio waves, microwaves, visible light and gamma rays. X-ray photons are highly energetic and have enough energy to … WebThe simplified electrical x-ray tube system defined in Figure 1 demonstrates the basic process of using a radiographic tube to generate x-ray. The potential gap of 20-150kV is generated between anode and cathode of x-ray tube by the x-ray machine [7]. A current through a filament at the cathode side is generated by a separate low voltage circuit. WebMethods: Basically, a monochromatic module was added to a conventional mammographic system. The monochromatic module can be mounted at the end of the x-ray tube and it consists of a curved HOPG (highly oriented pyrolytic graphite) crystal and a slit collimator. For image generation, the object is moved through the fan-shaped monochromatic ... devcrow
