A magnetic resonance imaging (MRI) scanner using a superconducting magnet. The magnet is inside the doughnut-shaped housing and can create a 3-tesla field inside the central hole. Superconducting magnets have a number of advantages over resistive electromagnets.
Magnetic resonance imaging ( MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing ...
Modern 3 tesla clinical MRI scanner. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and ...
The superconducting magnet is one of the main sources to supply a homogeneous main static magnetic field (B0) for MR imaging. Normally it ranges from 1 T to 7 T. To obtain mobility for a conventional MRI scanner that uses a superconducting magnet to supply B0, it is placed in a trailer. [4]
The biggest application for superconductivity is in producing the large-volume, stable, and high-intensity magnetic fields required for magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR). This represents a multi-billion-US$ market for companies such as Oxford Instruments and Siemens. The magnets typically use low-temperature ...
The lab develops technology, methodology, and applications at high magnetic fields through both in-house and external user activities. An in-house made 900 MHz (21.1 Tesla) NMR magnet has an ultra-wide bore measuring 105 mm (about 4 inches) in diameter, this superconducting magnet has the highest field for MRI study of a living animals.

Superconductivity is a set of physical properties observed in certain materials where electrical resistance vanishes and magnetic fields are expelled from the material. Any material exhibiting these properties is a superconductor. Unlike an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered, even ...
Magnesium diboride is the inorganic compound with the formula MgB 2. It is a dark gray, water-insoluble solid. The compound has attracted attention because it becomes superconducting at 39 K (−234 °C). In terms of its composition, MgB 2 differs strikingly from most low-temperature superconductors, which feature mainly transition metals.
