On the afternoon of July 29, 2017, by guangdong radiation medicine diagnosis quality control center and the radiation protection in guangdong province association of professional committee of the medical radiation protection hosted "to reduce the radiation dose, establish green scan" CT radiation protection safety and radiation dose management academic exchange in nanfang hospital, southern medical university academic training floor conference room was held successfully. Radiation protection association RongMingHai in guangdong province, deputy director of the guangdong environmental protection bureau of nuclear safety place ling-feng kong, nanfang hospital, southern medical university image yi-kai xu, director of the center, radiation medical radiation protection professional committee members and province medical institutions personnel attended the meeting.

        Bayer image division in the southern district of clinical specialist yong-cai Chen Radimetrics intelligent information platform is introduced, through the automatic data collection, recording and analysis of the history of patients with radiation dose and dose contrast agents, it is concluded that a more reasonable and effective follow-up radiation inspection scheme, let the victim in a clear understanding of the data at the same time, also provide a scientific basis for optimization scanning solution for doctors, promote the standardization and standardization of quality management, reduce the risk of patients with radiation.
