Hi there, I’m Xinrui “Ryan” Jiang, a master’s student in EE at Stanford University. Prior to that, I received my B.Eng from Fudan University. During my undergraduate study, I was fortunate to be advised by Professor Zhengzhong Tu at Texas A&M University and Professor Berkin Bilgic at Martinos Center for Biomedical Imaging/Harvard Medical School.

My work focuses on generative AI, agentic AI, and low-level vision. I enjoy the process of formalizing complex real-world challenges into optimization problems, and deriving actionable solutions with data-driven computational methods.

NLCG-Net: A Model-Based Zero-Shot Learning Framework for Undersampled Quantitative MRI Reconstruction

Xinrui Jiang, Yohan Jun, Jaejin Cho, Mengze Gao, Xingwang Yong, Berkin Bilgic

Presentation

  • We purposed NLCG-Net, a model-based and data-driven framework achieved via self-supervised learning, which incorporates nonlinear conjugate gradient optimization and Neural Network Regularization in a iterative manner and achieves zero-shot quantitative MRI reconstruction. T1, T2 mapping results on phantom and in-vivo data demonstrates NLCG-Net’s superiority on estimation quality at high acceleration.

🌟 Fun

In my spare time, I enjoy running (~5km each time), making LEGO figure, and playing with my cat Dafu (he is an American Shorthair)
