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


Record a bi-planar radiogram of two perpendicular planes of a metal pin which cannot be seen.

Determine the true length of the pin by taking into account the magnification factor which results from the divergence of the X-rays.

Determine the spatial position of the pin.
