4b). Note that it is possible to convert the gradiometry map into an improved static field map through integration and weighted averaging in k-space (Fig. 4c and Methods). See Supplementary Fig. 6 for the reverse process, where a B0 image is converted into a B1 image. Fig. 4: ...
The field is aligned to within 0.1 degrees using a thermal echo sequence18. Electron and nuclear spins The sample was previously characterized in Abobeih et al.18 and the 27 nuclear spins imaged in that work are a subset of the 50 nuclear-spin network presented here. The NV electron spin ...

6.21a) and can be used to map the proton coupling pathways. This is most clearly seen at the C3 shift of ring B, from which the H3 proton produces TOCSY correlations to all other protons in the ring, with the exception of H1 (which in this case had zero coupling with H2, thus ...
(b) a high-quality reference anatomy (in which gray and white matter can be automatically segmented such that the white-matter surface can be computationally inflated for clear depiction of visual field map organization) and (c) minimal distortion in the functional data to facilitate co-...

a method for amplitude of radiofrequency field inhomogeneity correction by acquiring an additional stimulated-echo-planar image with minimal mixing time, calculating the difference between the spin echo and the stimulated echo and multiplying the stimulated-echo-planar image by the inverse functional map...
The Er3+spin coherence time,T2, is probed via Hahn-echo measurement. The magnetic field is tuned to the resonance of the primary peak atB= 0.102 T (Fig.3a) under the applied 9.7 GHz microwave frequency. The echo signal is predominantly from the166Er electrons with only 3.6% of the signa...
