25 Αυγ 2014 · The document describes the key components of an X-ray machine: 1. The X-ray tube which produces X-rays and contains a cathode and anode in a vacuum tube housed in a protective casing. 2. The operating console which controls the voltage, current, and exposure time of the X-ray tube. 3.
5 Φεβ 2015 · This document summarizes the key components of an X-ray system, including the operating console, high frequency generator, and X-ray tube. It describes the internal parts of the X-ray tube, such as the cathode and anode.
The x-ray generator provides operator control of the radiographic techniques, including tube voltage (kVp), tube current (mA), and exposure duration , and delivers power to the x-ray tube.
1 Σεπ 2004 · Electromagnetic radiation travels at a velocity, C, of 3.0 × 10 8 m/s in a vacuum. The velocity in a vacuum is constant but will vary slightly in other materials. The distance traveled by 1 cycle is the wavelength, λ, typically described in units of nanometers (10 −9 m).
All photons move at the same velocity, c, in a vacuum, given by c = 2.998 108 m/s. b. Relationship between wave length and frequency. c. The propagation of X-rays. Similarly to visible light, X-rays propagate linearly. The rays from a point source form a divergent beam.
18 Απρ 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.
