The Superconductivity Research Center of the Korea Electrotechnology Research Institute (KERI, President Gyu-ha Choe) under the Ministry of Science and ICT has developed a superconducting insulation technology that can significantly reduce the size and weight of medical magnetic resonance imaging (MRI) equipment.
While many hospitals, both domestic and international, face many difficulties in facility management due to the large size and heavy weight of MRI equipment, the development of this technology, led by the team of Dr. Seog-Whan Kim and Dr. Young-Sik Jo of the Superconductivity Research Center, is expected to receive much attention.
MRI transmits a high frequency magnetic field of thousands of hertz to the human body, and displays the image signals generated from atomic nuclei in the body in a 2D or 3D cross-sectional image.
Resolution is the most important thing for an accurate MRI diagnosis, and a stronger magnetic field results in better quality.
Most existing MRIs use a superconducting electromagnet to create a powerful magnetic field.
Superconductivity is the phenomenon where metal or a compound is cooled below a certain temperature has almost no resistance to current flow.
