What Is the Use of Tungsten Wire in MRI?

Tungsten wire is commonly used to make RF (radio frequency) coils in magnetic resonance imaging (MRI). RF coils are an important part of MRI equipment and are used to generate and receive RF signals to generate MRI images. In MRI, the main uses of tungsten wire include the following aspects:

Coil Manufacturing: Tungsten wire can be used to manufacture coil elements in RF coils. These coils are used to generate RF pulses to excite nuclear spins in the sample being examined, and to receive the RF signals produced by the sample. The tungsten wire in the coil is often used as the wire for the coil element because it has good electrical conductivity properties and can transmit high-frequency RF signals.

Coil Holders: Tungsten wire can also be used in the supports and structures of RF coils. Coils require support and positioning to ensure accurate imaging. Tungsten wire is suitable for use in the structural parts of coils due to its strength and heat resistance.

Coupling and Shielding: In MRI coils, tungsten wire is also used to couple and shield elements. Different parts of the coil require precise positioning and connection, and tungsten wire can be used to ensure connections between the various elements of the coil. In addition, tungsten wire can also be used to shield coils to reduce the impact of external interference on MRI signals.
