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…
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…
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…
Physics-Informed Deep Unrolled Network for Portable MR Image Reconstruction
Efe Ilıcak, Chinmay Rao, Chloé Najac +6
Magnetic resonance imaging (MRI) is the gold standard imaging modality for numerous diagnostic tasks, yet its usefulness is tempered due to its high cost and infrastructural requir…
An imageless magnetic resonance framework for fast and cost-effective decision-making
Alba González-Cebrián, Pablo García-Cristóbal, Fernando Galve +5
Magnetic Resonance Imaging (MRI) is the gold standard in countless diagnostic procedures, yet hardware complexity, long scans, and cost preclude rapid screening and point-of-care u…
Zero-echo-time sequences in highly inhomogeneous fields
Jose Borreguero, Fernando Galve, José Miguel Algarín +1
Zero echo time (ZTE) sequences have proven a powerful tool for Magnetic Resonance Imaging (MRI) of ultrashort T2 tissues, but they fail to produce useful images in the presence of…
Elliptical Halbach magnet and gradient modules for low-field portable MRI
Fernando Galve, Eduardo Pallás, Teresa Guallart-Naval +8
Objective. To develop methods to design the complete magnetic system for a truly portable MRI scanner for neurological and musculoskeletal (MSK) applications, optimized for field h…
MaRGA: a Graphical and Application Interface for MaRCoS
J. M. Algarín, T. Guallart-Naval, J. Borreguero +2
