According to the British engineer website reported recently, UK Bristol university and university of swan lake is researching a X-ray sensor which can prevent doctor from error treatment for cancer radiotherapy patient. The sensor can raise alarm to remind doctor to stop light when X-ray illuminates in normal organization of patients.

    The sensor’s research is based on in physics study used to detect charged particles sensor, according to the design requirements, the sensor placed between patients and medical x-ray machine must be designed very shin, so it will not affect normal illuminates by medical x-ray. The sensor not only can detect 0.0001% intensity of ray radiation but also convenient doctor to adjust X-ray’s shape and strength by sensor’s collimator, which make X-ray hitting tumor location more accurately.

    Besides, 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 prevent error treatment. The project got funded   from British national health institutes, expected the sensor in the final product will be putted into use in hospitals within three years.
