Determination of Length and Position of an Object Which Cannot Be Seen

SKU: EDV-P2542005


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.


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


• 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
