This study presents NMR signal detection by means of a superconducting channel consisting of a Nb surface detection coil inductively coupled to a YBCO mixed sensor. The NMR system operates at a low-field (8.9mT) in a magnetically shielded room suitable for magnetoencephalographic (MEG) recordings. The main field is generated by a compact solenoid and the(More)
Introduction. Mobile unilateral magnets have been developed in the past ten years to investigate samples that cannot be moved or do not fit within the bore of traditional MRI scanners [1]. We have designed a novel device (see fig. 1) based on an elliptical magnet with a large free space at the centre of the magnet to host the entire coil system and,(More)
It is described the realization of a single sided scanner suitable for Nuclear Magnetic Resonance (NMR). A new design of a hand-size elliptical magnet, coil system and electronics is presented. First results demonstrate the possibility to measure relaxation times and diffusion coefficient in a small volume and open the possibility to use the prototype for(More)
In recent years, ultra-low field (ULF)-MRI is being given more and more attention, due to the possibility of integrating ULF-MRI and Magnetoencephalography (MEG) in the same device. Despite the signal-to-noise ratio (SNR) reduction, there are several advantages to operating at ULF, including increased tissue contrast, reduced cost and weight of the(More)
In recent years, Ultra Low Field (ULF) Magnetic Resonance Imaging (MRI) is being given more and more attention, thanks to the possibility of integrating ULF-MRI with MagnetoEncephaloGraphy (MEG) in the same set-up. A MEG-compatible Very Low Field (VLF) MRI device working in the hundreds of kHz, without sample prepolarization and with room temperature(More)
