EXPLORER X was developed by Professor Ren Qiushi and over ten PhD students from the Molecular Imag- ing Laboratory of Peking University after several years of research. It aims to utilize multispectral fundus imaging technology to achieve oxygen metabolism and hemodynamic analysis, and is equipped with pupillary light reflex and eye movement examination functions, enabling a multimodal examination approach that combines the eye, brain, and heart. This system is a global first.
