Limitations of the figure
Apply only to MRI systems with NdFeB permanent magnets. Superconducting MRI systems must not be included by default.
Original application & recovery
Where magnets are located in permanent-magnet MRI systems
Its position within the device helps with identification, but does not in itself establish the alloy, weight or eligibility for purchase.
Location within the equipment
In the scanner’s large permanent-magnet system and its magnetic return yoke. The system design must be clearly identified before any quantity is assumed.
System boundary
NdFeB per confirmed permanent-magnet MRI scanner. Foreign parts, housings, shafts, back irons, supports and other device components are not automatically included in the magnet mass.
Record before submitting an enquiry
- Verify the scanner type and magnet design from documentation
- Clarify the medical-device, ownership and decommissioning status
- Do not dismantle powerful large magnets yourself
