A wearable, stretchable radio-frequency coil for extremity imaging in low-field MRI systems
Jesús Conejero, Marina Fernández-García, José Borreguero +10
Purpose: To develop a wearable, stretchable radio-frequency (RF) coil that conforms to the extremities and improves the filling factor in low-field MRI. Methods: A stretchable sole…
Comment on electromagnetic noise cancellation in low-field MRI systems (arXiv:2509.05955v1, 2406.17804v3, 2210.06730v2, and related works)
Joseba Alonso, José M. Algarín, Teresa Guallart-Naval
In this Comment, we discuss recent approaches to electromagnetic interference (EMI) mitigation in low-field Magnetic Resonance Imaging (LF-MRI), as presented in arXiv preprints 250…
High-resolution ultra-low-field MRI with SNRAware denoising
Teresa Guallart-Naval, Hui Xue, José M. Algarín +8
Ultra-low-field (ULF, <0.1 T) magnetic resonance imaging (MRI) systems offer advantages in cost, portability, and accessibility, but their current utility is still limited by low s…
In-vivo imaging with a low-cost MRI scanner and cloud data processing in low-resource settings
Teresa Guallart-Naval, Robert Asiimwe, Patricia Tusiime +16
Purpose: To demonstrate in-vivo imaging with a low-cost, low-field MRI scanner built and operated in Africa, and to show how systematic hardware and software improvements can mitig…
Qualitative and quantitative hard-tissue MRI with portable Halbach scanners
Jose Borreguero, Luiz G. C. Santos, Lorena Vega Cid +14
Purpose: To demonstrate the feasibility of performing in-vivo imaging and quantitative relaxation mapping of soft and hard tissues using a low-cost, portable MRI scanner, and to es…
Subject grounding to reduce electromagnetic interference for MRI scanners operating in unshielded environments
Beatrice Lena, Bart de Vos, Teresa Guallart-Naval +6
Purpose. Portable low-field (< 0.1 T) MRI is increasingly used for point-of-care imaging, but electromagnetic interference (EMI) presents a significant challenge, especially in uns…
Electromagnetic Noise Characterization and Suppression in Low-Field MRI Systems
Teresa Guallart-Naval, José M. Algarín, Joseba Alonso
Purpose: Low-field MRI systems operate at single MHz-range frequencies, where signal losses are primarily dominated by thermal noise from the radio-frequency (RF) receive coils. Ac…
