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.
An x-ray is very similar to the light rays that our eye can perceive, except that they have much higher energy. This higher energy corresponds with their shorter wavelength. To generate an x-ray, a cathode is heated to a high temperature.The heat causes electrons to break away from the cathode.he patient is positioned between the x-ray machine and the film. It is the x ray technician's job to properly align the patient in space in order to capture the appropriate 2-D plane. Areas not of interest should be appropriately shielded. After the beam is activated, the film is shown to the radiologist.
