Nuclear medicine is a discipline that uses radionuclides for diagnosis, treatment, and research, generally divided into clinical nuclear medicine and basic nuclear medicine. Novel Medical, in collaboration with the Department of Engineering Physics at Tsinghua University, has developed cornerstone diagnostic equipment for molecular imaging such as SPECT (/CT), and preclinical research equipment like small animal PET/SPECT/CT. These products are currently used in many medical institutions nationwide and have received widespread acclaim from clinical experts.
