Medical X-Rays machine Overview

   There are many kinds of medical x ray machines.Every hospital has some models of x ray machines.Different Medical departments have different medical x ray machine.

    Please allow me to introduce some for you.The medical x ray machines can be classified into two group:diagnostic medical x ray machine and Treatment of X ray machine.I will introduce you the diagnostic medical x ray machine.The diagnostic medical x ray machines have mobile x ray machine,portable x ray machine,mobile c arm x ray machine,digital x ray machine,remote-control fluoroscopic equipment and so on.These medical x ray machines have been widely used in different medical departments.And they have many benefits to doctors.Doctor use them can make diagnostic much easier.

    From broken bones to life threatening illnesses, x-ray machines help diagnose and treat numerous medical conditions. In fact, seven out of ten people receive either a medical or dental x-ray every year.

    Literally thousands of x-ray machines are used daily in medicine and industry for examinations, inspections, and process controls. Because of their many uses, x-rays are the single largest source of man-made radiation exposure.

    In a clinic setting you are most likely to encounter radiation from a diagnostic x-ray. X-rays pass more easily through the soft tissues of our bodies than through our bones and organs. After passing through our body, x-rays strike a special x-ray film, creating an image showing shadows where our bones, organs and other dense masses have absorbed x-rays.

    Like microwaves, radio waves, and visible light, the x-rays produced by an x-ray machine are a form of electromagnetic radiation. Unlike microwaves, radio waves, and visible light, x-rays are ionizing radiation, which is capable of removing electrons from atoms and damaging living cells and the DNA of those cells. However, since x-ray machines only produce radiation during operation and the amount of radiation used is small, resulting medical problems are unlikely.

X-ray checking may cause cancer

    Most of hospitals donn't have any protecting measures when patients do X-ray checking. But according to International radiation protection committee's research shows, there are 350 people causing cancer, leukemia or other genetic disease because of checking x-ray in a ten million population city. It is also that the state ministry has specific provision: doctors should adopt shielding protection of near x-ray irradiation sensitive organs when do diagnosis and treatment on patients. Then many hospitals don't perform it.

    There are a lot of people waiting for doing Computed Tomography checking in big hospitals of Beijing. But the patients were not told to wear protecting clothing. Then in foreign, if doctor want to do x-ray checking on teeth, the patient will wear protecting clothing for them before doing X-ray checking, doctors will introduce x-ray radiation process in detail and wear heavy lead protective clothing for patients and cover neck, breast and genital. In addition, patients should wear protective hoods. Every thing is ready and doctor will begin.

    For X-ray demage, Oxford University and British cancer reseach center research shows that there are 0.6% new cancer cases in British, Germany is 1.5% and Japan is 3.2%. It is caused by X-ray and Computed Tomography. It is most damage for pregnant women and children and it not only injure children’s mental development but also result in fetal abnormalities.

   In accordance with China medical association and radiation society, conventional check radiation is in the scope of human safety. But we should avoid unnecessary CT checking or x-ray checking. If you go to hospital, whether decide x-ray or not according to disease and not ask to do it positivly. You can ask whether MRI or B Ultrasound and other ways can achieve the same effect. You had better choose small radiation and ensuring the inspection effect methods. In addition, patients can request anti-radiation activly before checking. Last one, if no necessary, don’t go into neurobehavior exam.

X-Ray Exams of the Digestive Tract(3)

      Then we continue to introduce some knowledge that is necessary to know when you have got an exam by x ray machine.
 
      Firstly , you may ask, are there GI test safe?
 
      There is virtually no risk with the upper and lower GI tests, unless they are repeated several times within a few months' time, when radiation exposure can become a risk. Although radiation exposure is minimal, it is greater than for standard still X-rays. Steps will be taken during the test to minimize radiation exposure.
 
      Other risks include: 1.Infection (very low risk with both the upper and lower GI tests). 2. Tearing the intestinal wall during a lower GI test. Should this occur, surgery may be necessary. This is a very rare complication.
And then who should not receive GI Tests?

      If you have an existing blockage or tear in the intestinal wall, the upper and lower GI tests should not be performed.If you are pregnant or think you might be pregnant, you should not have these tests unless absolutely medically necessary. Talk to your doctor about other tests that can be more safely performed to diagnose your problem during pregnancy.
