Frequently Asked Questions

Why must gradient coil supports be non-magnetic?

Non-magnetic materials prevent interference with the MRI's magnetic field, ensuring image quality and preventing artifacts in diagnostic imaging.

How does thermal expansion affect gradient coil performance?

Thermal expansion can alter coil geometry, changing gradient field characteristics and potentially causing image distortion. Low-expansion materials maintain dimensional stability.

What maintenance is required for structural supports?

Regular inspection for cracks, deformation, or loose fasteners; periodic verification of dimensional tolerances; and cleaning to prevent conductive particle accumulation.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
