Tags:
Department(s)/lab(s): School of Physics and Astronomy / Sir Peter Mansfield Imaging Centre | SPMIC (Centre Director) @ Nottingham
Summary:

Bowtell directs the SPMIC and leads hardware development for biomedical imaging, including the gradient/shim and bi-planar coil systems and magnetic-shielding/field-nulling that make wearable OPM-MEG possible, alongside ultra-high-field MRI. The work complements NV-center diamond ensemble quantum sensing (DEER, NMR, T1 relaxometry) at pT/sqrt(Hz) sensitivity by pursuing the same field-sensing goals in a different physical platform.

Department(s)/lab(s): School of Physics and Astronomy / Sir Peter Mansfield Imaging Centre | Brookes Group (SPMIC MEG/OPM) @ Nottingham
Summary:

Holmes develops the magnetic-shielding, active field-nulling and sensor-calibration technology that enables free movement during OPM-MEG, and is Chief Scientist / co-founder of Cerca Magnetics. The work complements NV-center diamond ensemble quantum sensing (DEER, NMR, T1 relaxometry) at pT/sqrt(Hz) sensitivity by pursuing the same field-sensing goals in a different physical platform.

Department(s)/lab(s): Department of Imaging Neuroscience (FIL) | UCL OPM-MEG (Dept. of Imaging Neuroscience) @ UCL
Summary:

Mellor works on magnetic-field mapping and movement-artefact correction for moving OP-MEG and on ictal/clinical OP-MEG recordings. The work complements NV-center diamond ensemble quantum sensing (DEER, NMR, T1 relaxometry) at pT/sqrt(Hz) sensitivity by pursuing the same field-sensing goals in a different physical platform.
