resistive magnet |
| 释义 |
resistive magnet resistive magnet An MRI term for a conventional magnet that generates a magnetic field based on principles of electromagnetism, and requires large current values and significant magnet coil cooling. Resistive magnets are typically limited to maximum field strengths of ± 0.6T.
Types
• Iron-core electromagnets—Vertically-oriented magnetic field, limited fringe field, little missile effect due to the closed iron-flux return path.
• Air-core electromagnets—Horizontally oriented fields with large fringe fields (unless magnetically shielded); prone to missile effects. |
