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.
Here are the basics of how it works. 1  There is an X-ray generator, a device that produces the radiation by means of an X-ray tube as described above. 2  There is a device that detects the X-rays â nowadays this will typically be a digital X-ray detector (such as a flat panel detector), but could perhaps be a photo film.
