Professor Yiqiao Song from Harvard University and Massachusetts General Hospital visited APM

    On January 22, 2024, Professor Yiqiao Song was invited to visit the Innovation Academy for Precision Measurement Science and Technology (APM) of Chinese Academy of Sciences and gave a lecture entitled "Miniaturization of Magnetic Resonance". The lecture was chaired by Dean Prof. Xin Zhou.

    Prof. Song graduated from Peking University and got the Ph.D. at Northwestern University. After that, he worked as a postdoctoral fellow at the University of California, Berkeley. Now he is a Research Scientist at Harvard University and research staff in Massachusetts General Hospital. Prof. Song is a Fellow of the American Physical Society and International Society of Magnetic Resonance, Associate Editor of Frontiers of Physics, the Journal of Magnetic Resonance and Petroleum Sciences, member of the editorial boards at Magnetic Resonance Letters and the Chinese Journal of Magnetic Resonance. He is also the chair of the Magnetic Resonance in Porous Media Division of Groupement Ampere. His research focuses on developing NMR/MRI methodologies and instrumentation for diverse applications.

    In the lecture, Prof. Song discussed the miniaturization of NMR by using ASIC (application-specific integrated circuit) chips, to encapsulate all essential functions of NMR spectrometers in a chip. Firstly, he introduced the relevant physics to perform NMR measurements, outlined the requirements of the NMR system, and discussed the ASIC designs. Experimental data were presented to showcase the miniaturized NMR system's ability to characterize a wide range of materials. He highlighted the system's ability to perform complex NMR experiments, such as two-dimensional experiments that are crucial for complex natural materials and biological tissues.

    After the lecture, Prof. Song visited the 1.5T, 3T, 9.4T MRI laboratories and the Zero to Ultra-Low Field NMR Laboratory.
