The x-rays cannot turn corners. From the standpoint of image quality, the fact that x-rays only travel in straight lines is what enables us to produce an image that accurately represents the patient’s body.
- X-rays are created by radiation coming from electrons. X-rays are a type of light. When they’ve been excited, atoms emit packages of energy called photons.
- X-rays are used to look at especially tiny structures because they have a shorter wavelength than visible light. The shortest wavelengths of visible light—what we see as violet—measure somewhere around 400 nanometers.
- There’s a big difference between “soft” and “hard” X-rays. Soft X-rays carry far less energy than hard X-rays, and are for this reason more easily absorbed by air and especially by other mediums.
- X-rays were discovered by accident. X-rays, originally named Röntgen rays, were discovered in 1895 by German physicist Wilhelm Röntgen. Röntgen had been doing experiments with cathode rays—streams of electrons in vacuum tubes.
Feb 3, 2023 · X-rays are commonly used to diagnose problems with the spine. Some of the most common conditions that can be diagnosed with spinal X-rays include: Fractures or dislocations: X-rays can help diagnose fractures or dislocations of the vertebrae or other bones in the spine. Degenerative disorders: X-rays can help diagnose conditions such as ...

X-rays travel in straight lines and a beam of X-rays diverges from its source. Structures the beam hits first will be magnified in relation to those which are nearer the detector. To reduce magnification the X-ray source can be moved further away from the subject.

Aug 3, 2018 · Unlike the old X-ray films, which use X-rays directly to change the chemical properties of the X-ray film material, the modern detection systems first convert the X-rays to light and eventually to electrons.

If viewed from the front or exposure side, the side from which the X-ray beam originally entered the body, it will appear to be a left foot. But if the same image is looked upon from the back-the opposite surface or nonexposure side, the viewer sees the mirror image, which appears to be a right foot.
