How to prevent X-ray from hurting normal cells

   In modern medical field, all kinds of x ray equipments have been widely used in hospitals, health centers, clinical centers and so on.There are diagnostic equipments, such as mobile x ray machine,stationary x ray machine, c arm machine ect. The x ray technology brings much convenience to medical field, but as every one knows, overmuch x ray can do a lot of harm to human body.
      According to British engineer's website reported recently, UK Bristol university and university of swan lake is researching a X-ray sensor which can prevent doctors from incorrect treatment to cancer radiotherapy patient. The sensor can produce alarm to remind doctors to stop light when X-ray illuminates in normal patients.
      The sensor’s research is based on physics study used to detect charged particles sensor, according to design requirements, the sensor placed between patients and medical x-ray machine must be designed very shin, so it will not affect the normal illuminates by medical x-ray. The sensor can not only detect 0.0001% intensity of ray radiation but also is very convenient for doctor to adjust x-ray’s shape and strength by sensor’s collimator, which make x-ray hitting tumor location much more accurately.
      Besides, the research team is still developing related software which can predict the sensor’s possible problems in using process and compare to normal situation, so operators can find problems and can prevent incorrect treatment. It is expected that the sensor in the final product will be put into use in the hospitals within three years.
