A High-Dynamic-Range Digital RF-Over-Fiber Link for MRI Receive Coils Using Delta-Sigma Modulation

no code implementations27 May 2021 Mingdong Fan, Robert W. Brown, Xi Gao, Soumyajit Mandal, Labros Petropoulos, Xiaoyu Yang, Shinya Handa, Hiroyuki Fujita

Non-conductive transmission solutions based on fiber-optic cables are considered to be one of the alternatives, but are limited by the high dynamic range ($>80$~dB) of typical MRI signals.

Differentiable Combinatorial Losses through Generalized Gradients of Linear Programs

no code implementations18 Oct 2019 Xi Gao, Han Zhang, Aliakbar Panahi, Tom Arodz

When samples have internal structure, we often see a mismatch between the objective optimized during training and the model's goal during inference.
