An X-ray tube is a vacuum tube that converts electrical input power into X-rays. [1] The availability of this controllable source of X-rays created the field of radiography, the imaging of partly opaque objects with penetrating radiation. In contrast to other sources of ionizing radiation, X-rays are only produced as long as the X-ray tube is ...

18 kwi 2023 · This chapter describes the x-ray production process, characteristics of the x-ray beam, x-ray tube design x-ray generator components, and factors that affect exposure and exposure rate.
20 lut 2016 · The X-ray tube contains a vacuum in order to accelerate the electrons with maximum efficiency. The electrons are accelerated across a potential difference ranging from 40 to 120 kV in a diagnostic X-ray tube.
X-rays are produced within the X-ray machine, also known as an X-ray tube. No external radioactive material is involved. Radiographers can change the current and voltage settings on the X-ray machine in order to manipulate the properties of the X-ray beam produced.
X-ray machines produce x rays that pass through a patient's tissues and strike a digital receptor or film to make a radiographic image. The primary components of an x-ray machine are the x-ray tube and its power supply. The x-ray tube is positioned within the tube head, along with some components of the power supply (Fig. 1-5). An electrical ...
18 lip 2024 · The x-ray tube contains two principal elements: filament (also acts as cathode): boils off electrons by thermionic emission. target (also acts as anode): electrons strike to produce x-rays. Additional components include: expansion bellows (provide space for oil to expand) tube envelope (evacuated) tube housing. cooling dielectric oil. rotor.
