Q&A with Dongwook Lee and Jong Chul Ye

BY XIN MIAO

Dongwook Lee is currently a PhD student at the Korea Advanced Institute of Science and Technology (KAIST). He works on advanced image reconstruction techniques for dynamic MRI. His paper, selected as the Editor’s Pick for December, is entitled “Acceleration of MR parameter mapping using annihilating filter-based low rank Hankel matrix (ALOHA)”. ALOHA is a novel image reconstruction algorithm with the goal of clear, artifact free images acquired from very fast imaging schemes. For this paper, ALOHA was applied to accelerated MR parameter mapping, but could also be used for dynamic and parallel MRI, and even non-MR applications. We recently invited Dongwook and his supervisor, Dr. Jong Chul Ye, to talk about this paper.

Q&A with Li Feng and Ricardo Otazo

Dr. Li Feng and Dr. Ricardo Otazo are researchers at the New York University School of Medicine, whose paper on golden angle radial MRI with compressed sensing and parallel imaging is one of our Editor’s picks for the month of February. Li recently finished his doctorate at NYU, whereas Ricardo arrived in New York from the University of New Mexico, where he completed his PhD in 2007. They are both in love with what New York has to offer, academically as well as socially. We met over Skype to discuss XD-GRASP, ? free-breathing MR imaging framework that combines the acceleration capability of compressed sensing and the self-navigation properties of radial imaging to reconstruct dynamic motion-resolved multidimensional data.
