Abstract：Nuclear magnetic resonance imaging system, electric magnetometer, image enhancement or correction were quantitatively
identified as three key technical directions in the field of MRI through social network analysis of Derwent patent data. Then, Chinese
comprehensive strength in each key technology field was further studied successively with the help of five indicators, namely existing
technology accumulation, technological innovation activity, technology output capability, PCT applications, and highly cited patents
according to multidimensional data comprehensive analgsis. The results showed that Chinese competitiveness in the two fields of
MRI imaging system and electric magnetometer was relatively weak, and there was a risk of getting stuck. It is recommended that
while strengthening R&D and expanding the scale of technology, attention should be paid to the cultivation of high-value patents
and the output of patented technologies. Chinese competitiveness was second in the field of image enhancement or correction, and it
could continue to enhance its competitiveness through the implementation of a patent strategy.
