Simulated radiation levels and patterns of MRI without a Faraday shielded room

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose We characterize electromagnetic (EM) radiation patterns and levels in conventional MRI systems as a function of field strength and load symmetry, providing a framework for mitigation strategies allowing operation without a shielded room. Methods We simulated the far‐field radiation pattern and fields at a 10 m radius (|E|10m and |B|10m)

Quantum Ghost Imaging by Sparse Spatial Mode Reconstruction

open access: yesAdvanced Quantum Technologies, EarlyView.
Hermite–Gaussian spatial modes are used in quantum ghost imaging for enhanced image reconstruction, by exploiting modal sparsity. By leveraging structured light as a basis for imaging, time‐efficient and high resolution quantum ghost imaging is achieved, paving the way for breakthroughs in low‐light, biological science applications.
