“…Owing to close thermal contact between heater strip and coil, the temperature of each heater strip is less and near to the hot-spot of coil. All these observations manifested a reliable model of quench protection for 9.4 T field strength magnet to be used in MRI systems [8]. Design of MRI magnet having 9.4 T strength [8].…”

“…Quench has been enhanced through an active trigger heater. A detailed analysis based on this protection scheme has been performed with quench simulations of voltages, currents and temperatures [8]. Formation of 9.4 T magnet for MRI system is shown in figure 1 illustrating MC1, MC2, MC3, MC4 and MC5 as the main coils and CC1 through CC4 as compensation coils.…”

Superconductivity plays a vital role in advanced medical diagnostic as well as in treatment of cancer. Smaller sized superconducting cyclotrons are developing as efficient techniques with carbon ions and protons for external beam therapy. This equipment further gives benefits of less cost and due to smaller size it is far easier to handle. Nowadays, superconductivity has been used commercially in numerous applications in medical sciences including low-temperature superconducting (LTS) materials and high field magnets in magnetic resonance imaging (MRI), nuclear magnetic resonance (NMR), magnetic gene transfer, magnetic drug delivery system and cancer and internal hemorrhages detection. Almost all commercial medical systems based on superconductivity use LTS and the majority uses NbTi wires or superconducting quantum interference device (SQUID) made of LTS material.

“…The circular coils are used in MRI machines for magnetic field strength. Here, the coils act as receivers for the human body's radio frequency signals and transfer them to the computer for images [14]- [17]. The two coils are arranged at the required distance, and the current source is applied as per the electrical parameters.…”
