The X-Ray Imaging Model  simulates the basic concepts of X-Ray imaging, exploring how different aspects of both the X-Ray source as well as the sample affect the X-Ray image.  The simulation has a main window which contains the simulated image and the controls to manipulate the X-Ray characteristics and the physical characteristics of the sample to be imaged. In addition to the main panel, there are two optional windows. The first contains a graph of the X-ray spectrum and a second graph of the simulated exposure level of the film. The second optional window shows the geometry of the sample, which consists of a slab with two embedded cylinders within it.

The X-Ray Imaging Model was created by Michael Gallis using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. You can examine and modify this compiled EJS model if you run the model (double click on the model's jar file), right-click within a plot, and select "Open Ejs Model" from the pop-up menu. You must, of course, have EJS installed on your computer. 

Please note that this resource requires at least version 1.6 of Java (JRE).
