How use x ray macine?


X ray machine is a kind of medical equipment used to photograph patient's head, chest, stomach, lumbar and extremities.
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. When the X-rays hit the film, they expose it just as light would. Since bone, fat, muscle, tumors and other masses all absorb X-rays at different levels, the image on the film lets you see different (distinct) structures inside the body because of the different levels of exposure on the film.
Then I will tell something about how to use the xray machine.
1 Tell the patient to undress and put on an exam gown
2 Cover her with a lead apron
3 Bring the patient into the X-ray room. Place him between the X-ray camera and the film or the recorder.
4 Leave the room. Press the remote button to take the image.
5 Have a radiologist analyze the
X-ray images.
Following the above, you maybe have a breif recognization about how to use x ray machines.
Last but not least, the x radiography is harmful ,so you can not use it without professional help.
