Principle

This experiment provides training in determining the length and position of an object based on an X-ray image. A metal pin that is embedded in a wooden block is used as the model. This experiment is also an excellent preparatory exercise for demonstrating the principle of computed tomography.

Benefits

  • Simulation of a real-life situation in x-ray diagnostics
  • Application which trains three-dimensional thinking

Tasks

  1. Record a bi-planar radiogram of two perpendicular planes of a metal pin which cannot be seen.
  2. Determine the true length of the pin by taking into account the magnification factor which results from the divergence of the X-rays.
  3. Determine the spatial position of the pin.

Learning objectives

  • X-ray radiation
  • Bremsstrahlung
  • Characteristic radiation
  • Law of absorption
  • Mass absorption coefficient
  • Stereographic projection
