Sometimes, dyspepsia is a more sudden, noticeable (acute) sensation. Depending on the cause of the dyspepsia, people may have other symptoms such as a poor appetite, nausea, constipation, diarrhea, flatulence, and belching. For some people, eating makes symptoms worse. For others, eating relieves symptoms.
An X-ray machine is essentially a camera. Instead of visible light, however, it uses X-rays to expose the film. X-rays are like light in that they are electromagnetic waves, but they are more energetic so they can penetrate many materials to varying degrees.
Medical x-ray machines in hospitals use the same principle as the Crookes Tube to produce x-rays. The most common x-ray machines use tungsten as there cathode, and have very precise electronics so the amount and energy of the x-ray produced is optimum for making images of bones and tissues in the body.Here is a good page that shows how x-rays are formed. 1  Go on to page 7. 2  Go back to page 5.3  Return to the table of contents. 4  Return to the Radiation Information Network's HomePage.ere is a good page that shows how x-rays are formed. 1  Go on to page 7. 2  Go back to page 5. 3  Return to the table of contents. 4  Return to the Radiation Information Network's HomePage.
