학과 구성원 여러분의 많은 참석을 부탁드립니다.



○ 일시: 2018년 7월 20일(금) 오후 4:00

○ 연사: Prof. Yong-Jihn Kim (Department of Physics, University of Puerto Rico)

○ Title: Manufacturing next generation cryogen-free 1.5T MRI and cryogen-free NMR



○ Abstract:  Since the discovery of 39K superconductivity in MgB2 in 2001, people are working on manufacturing next generation cryogen-free 1.5T MRI and cryogen-free NMR. In 2007, Columbus Superconductors, ASG Superconductors, and Paramed Medical Systems indeed produced 0.5T cryogen-free Open MRI, employing MgB2 wires and two GM cryocoolers. However, its image quality is not good enough, compared to that of current NbTi-based 1.5T MRI, seriously limiting marketability. Cutting Edge Superconductor (CES) has the world’s best patented technology on MgB2 wire to improve its critical current, which enables cryogen-free 1.5T MRI and cryogen-free NMR. CES is collaborating with LUVATA, GE, Columbus Superconductors, BRUKER, and MIT. We report the current status of manufacturing next generation cryogen-free 1.5T MRI and cryogen-free NMR.
