Applications of Superconductor

Ultra Low- Field Magnetic Resonance Imaging (ULF-MRI):

Magnetic Resonance Imaging, designed a revolution in non-invasive imaging techniques, and the strategy is used globally for many diagnoses. MRI is allowed by the high magnetic areas that only superconducting magnet can generate. Step-by-step upgrades in the performance and cost of this recognized technology continue, but these days’ scientists are also creating a complementary strategy, Ultra-Low-Field MRI. In this new strategy, instead of a higher magnetic area from a superconducting magnet, a very low area - 10,000 times lower is used.

Magnetocardiography (MCG)

MRI into the medical care system has led to significant benefits. MRI provides an tremendous increase in diagnostic ability, clearly displaying soft cells features not noticeable using X-ray imaging. At the same time MRI can often eliminate the need for dangerous X-ray examinations. These benefits have decreased the need for exploratory surgery treatment. The availability to very accurate diagnostic and location information is causing the decrease in the level of intervention that is required.


Uses of Superconductor:

  • Maglev trains use superconductors to levitate the train above magnetic rails. This allows them to function without friction, and therefore acheive unprecedented rates of speed. The maglev train below is being set up at the Old Dominion School in Hampton, Virginia. It is the first to be set up in the US. 

  • MRI (Magnetic Resonance Imaging) devices use superconductors to provide a powerful enough attractive area so that hydrogen atoms in your body and water elements will pick up energy from the field which can then be recognized by special equipment. SQUIDS (Superconducting Quantum Interference Device) can be used like an MRI, but without the need for a strong magnetic field. They can identify magnetic fields of considerably small magnatudes. They can also be used for precise motion recognition.

  • Superconductors are used to create SQIDS. Magnetoencephalography is a method to create pictures of brain activity from the magnetic fields generated by electrical current in the brain. The magnetoencephalography program uses SQIDS to identify those magnetic fields. A superconductor is used to protect the system (and the patient's head) from all other magnetic fields such as the magnetic field of the earth and other electronics equipment in the room.
