Overcoming the limitations of NMR Field Probes: A Novel Integrated Sensor Utilizing Pre-Polarization for (Ultra) Low Field MRI
Pavel Povolni, Dominique Goerner, Praveen Iyyappan Valsala +9
Access to magnetic resonance imaging (MRI) remains severely limited in low- and middle-income countries, especially in sub-Saharan Africa, despite rising rates of non-communicable…

Group-kernel auto-calibration and group-patch k-space reconstruction: Fast MRI with time-variant B0 kernels partitioned into time-invariant subsets
Rui Tian, Martin Uecker, Oliver Holder +3
Purpose: Pushing MRI speed further demands more spatially-encoded information captured per unit time, e.g., by superimposing additional field modulations during oversampled readout…

Indirect Zero Field NMR Spectroscopy
Kai Buckenmaier, Richard Neumann, Friedemann Bullinger +11
This study pioneers the two-field correlation spectroscopy (COSY) in zero to ultralow field (ZULF) liquid state NMR, employing hyperpolarized [1-C]pyruvate as a model system…
