Structural Support Component – Computer, Electronic and Optical Product Manufacturing

Q: 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.

Q: 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.

Q: 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.
