WebbX-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. Different X-ray beam spectra are applied to different body parts. The X-ray tube WebbThe path difference 2 d sin (θ) can be determined from the diagram (Figure 1). The second condition is known as the Braaq condition. An x-ray beam with wavelength 0.130 nm is directed at a crystal. As the angle of incidence increases, you observe the firs strong interference maximum at an angle 22. 5 ∘.

WebbThe incident X-ray beam, with wavelength λ, shown as a white line, "creates" an imaginary Ewald's sphere of diameter 2/λ (shown in green). The reciprocal lattice ( red points ) rotate as the crystal rotates, and every time that a reciprocal point cuts the sphere surface a diffracted beam is produced from the center of the sphere (yellow arrows). WebbAn x-ray beam contains many x-rays that possess only very low energy, which will contribute nothing to the x-ray image and will only increase the radiation exposure to the patient. They are too weak to penetrate through body tissues and interact with the film or image receptor.
