This application chronicles the history and discovery of the X-Ray and it's uses. For example:
In late 1895, a German physicist, W. C. Roentgen was working with a cathode ray tube in his laboratory. He was working with tubes similar to our fluorescent light bulbs. He evacuated the tube of all air, filled it with a special gas, and passed a high electric voltage through it. When he did this, the tube would produce a fluorescent glow. Roentgen shielded the tube with heavy black paper, and found that a green colored fluorescent light could be seen coming from a screen setting a few feet away from the tube. He realized that he had produced a previously unknown "invisible light," or ray, that was being emitted from the tube; a ray that was capable of passing through the heavy paper covering the tube. Through additional experiments, he also found that the new ray would pass through most substances casting shadows of solid objects on pieces of film. He named the new ray X-ray, because in mathematics "X" is used to indicated the unknown quantity.
This is the Free Beta version and it will be constantly revised. Please rate and offer critiques. I will be uploading a formula, positioning, history, and physics app soon. Ultimately I want to combine all of these mini apps and produce what I will think will be a very useful and handy reference guide to all Radiology Tech students and current Radiology Technologists. As of right now though this is how I shall fine tune the apps and make them worthy of the Imaging public. Also please feel free to donate. Any thing and everything helps.
Again, these will be updated when I am done with the original apps. Then more info and graphics will be installed.
