How to Reduce Risk Form X Ray

   Consumers have an important role in reducing radiation risks from medical X-rays. FDA recommends these steps:


     Ask your health care professional how an X-ray will help. How will it help find out what's wrong or determine your treatment? Ask if there are other procedures that might be lower risk but still allow a good assessment or treatment for your medical situation.


      Don't refuse an X-ray. If your health care professional explains why it is medically needed, then don't refuse an X-ray. The risk of not having a needed X-ray is greater than the small risk from radiation.


      Don't insist on an X-ray. If your health care professional explains there is no need for an X-ray, then don't demand one.


      Tell the X-ray technologist in advance if you are, or might be, pregnant.


      Ask if a protective shield can be used. If you or your children are getting an X-ray, ask whether a lead apron or other shield should be used.


      Ask your dentist if he/she uses the faster (E or F) speed film for X-rays. It costs about the same as the conventional D speed film and offers similar benefits with a lower radiation dose. Using digital imaging detectors instead of film further reduces radiation dose.


      Know your X-ray history. "Just as you may keep a list of your medications with you when visiting the doctor, keep a list of your imaging records, including dental X-rays," says Ohlhaber. When an X-ray is taken, fill out the card with the date and type of exam, referring physician, and facility and address where the images are kept. Show the card to your health care professionals to avoid unnecessary duplication of X-rays of the same body part. Keep a record card for everyone in your family.

Image fusion wil promote medical image development

    From PET/CT developed in 2003, medical image has been in the trend of fusion continually. As one of the fastest discipline, in recent several years, radiation, ultrasound and nuclear medicine have achieved the rapid development, but there are less and less reling on a single imaging technology to diagnose and it more depends on multiple imaging results to observe and compare in different image, so that get comprehensive image diagnosis result.


      In past, we want to the fusion, now we are doing fusion and it is fused in the future. At present, comprehensive image is more and more important and fuse different image advantage and improve the comprehensive level of subject and increase medical imaging competitiveness and it is good for promote sustainable development of medical image industry.

     Recently, fusion trend of medical image has been obvious gradually and it is less and less reling on a single imaging examination technology to make the diagnosis. In addition, medical image fusion has not only meet itself development needs and meet medical clinical diagnosis demands but also it can observe and compare and analyse in different images so that it can provide with image information of different angle and so make the correct diagnosis.


      Medical image fusion is that medical information fusion and information fusion technology is applied in medical imaging fields. In the other words, using computer technology do digital integrated treatment for image information obtained from various imaging examination.


      Image fusion need better fusion, including all kinds of medical imaging diagnostic technology, such as x-rays, ultrasound, nuclear science, optical and play different image technology advantage fully and make up for the shortage of single check imaging. Fusion technology can be devide into two parts: One is belong to diagnosis and the other exists for treatment. As the diagnosis of fusion technology, it appears vascular Computed Tomography, Vascular MR; On treatment, there are intervention study and ultrasound doing fusing; Even, the X-ray, ultrasound and magnetic resonance imaging (mri) together for treatment.


      But if medical fusion want to get breakthrough development, it needs to be established in the digital network. Data network provide with technology method and technology platform for improving the diagnostic efficiency and quality of the diagnosis.


      From the global Global medical imaging market demand to see, the market demands of some developed countries have already been close to the saturated, but in developing countries, especially Latin America, the Middle East, southeast Asia and Africa, their market demands are still large. According to related data, in 2011, the total market of our country medical image equipments achieved 1.82 billion dollars and it is forecasted that it will achieve 2.65 billion dollars.


      China government has promoted basic-level medical development and pull market demand of ultrasound, X-ray machine, DR image equipment, but the future medical development will give priority to the primary medical treatment and senior medical treatment. Therefore, medical imaging equipmenthas increased in the field of high medical treatment.

Facial X-Ray

     A facial X-ray is a series of pictures of the bones in your face. One type of facial X-ray (called a paranasal sinus X-ray series) looks at the air-filled cavities (sinuses) around the nose and eyes.


      X-rays are a form of radiation, like light or radio wave, that are focused into a beam, much like a flashlight beam. X-rays can pass through most objects, including the human body. X-rays make a picture by striking a detector that either exposes a film or sends the picture to a computer. Dense tissues in the body, such as bones, block (absorb) many of the X-rays and look white on an X-ray picture. Less dense tissues, such as muscles and organs, block fewer of the X-rays (more of the X-rays pass through) and look like shades of gray on an X-ray. X-rays that pass only through air look black on the picture.


      See a picture of the bones of the face.


      A facial X-ray helps find bone fractures, tumors, foreign objects, infections, and abnormal growths or changes in bone structure or size. An X-ray of the eye (orbital cavity) may be taken if the eye has been injured. A computed tomography (CT) scan may be needed to check any problems seen on X-ray.
