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…
ezyMRI: How to build an MRI machine from scratch -- Experience from a four-day hackathon
Shaoying Huang, José Miguel Algarín, Joseba Alonso +25
Nuclear magnetic resonance instruments are becoming available to the do-it-yourself community. The challenges encountered in the endeavor to build a magnetic resonance imaging inst…
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
The open-source console MaRCoS, which stands for "Magnetic Resonance Control System", combines hardware, firmware and software elements for integral control of Magnetic Resonance I…
MaRCoS, an open-source electronic control system for low-field MRI
Vlad Negnevitsky, Yolanda Vives-Gilabert, José M. Algarín +7
Every magnetic resonance imaging (MRI) device requires an electronic control system that handles pulse sequences and signal detection and processing. Here we provide details on the…
Benchmarking the performance of a low-cost Magnetic Resonance Control System at multiple sites in the open MaRCoS community
T. Guallart-Naval, T. O'Reilly, J. M. Algarín +9
Purpose: To describe the current properties and capabilities of an open-source hardware and software package that is being developed by many sites internationally with the aim of p…
Portable magnetic resonance imaging of patients indoors, outdoors and at home
T. Guallart-Naval, J. M. Algarín, R. Pellicer-Guridi +15
Mobile medical imaging devices are invaluable for clinical diagnostic purposes both in and outside healthcare institutions. Among the various imaging modalities, only a few are rea…
Prepolarized MRI of Hard Tissues and Solid-State Matter
J. M. González, J. Borreguero, E. Pallás +9
Prepolarized Magnetic Resonance Imaging (PMRI) is a long-established technique conceived to counteract the loss in signal-to-noise ratio (SNR) inherent to low-field MRI systems. Wh…
A Fast 0.5T Prepolarizer Module for Preclinical Magnetic Resonance Imaging
J. P. Rigla, J. Borreguero, C. Gramage +11
We present a magnet and high power electronics for Prepolarized Magnetic Resonance Imaging (PMRI) in a home-made, special-purpose preclinical system designed for simultaneous visua…
Peripheral Nerve Stimulation limits with fast narrow and broad-band pulses
D. Grau-Ruiz, J. P. Rigla, E. Pallás +12
Peripheral Nerve Stimulation (PNS) constrains the clinical performance of Magnetic Resonance and Particle Imaging (MRI and MPI) systems. Extensive magneto-stimulation studies have…
Simultaneous imaging of hard and soft biological tissues in a low-field dental MRI scanner
J. M. Algarín, E. Díaz-Caballero, J. Borreguero +12
Magnetic Resonance Imaging (MRI) of hard biological tissues is challenging due to the fleeting lifetime and low strength of their response to resonant stimuli, especially at low ma…
