Co to jest Robot MRI- Compatible?

Operating a robot inside or near an MRI scanner is far frem trivial. Thee system must function relieable in a strong static magnetic field (typically 1.5 T or 3 T), rapidly chansincing gradient fields, and radiofrequency (RF) pulses. Any ferromagnetic contexent can contache a dangerous projectie, and even non- ferromagnetic metals cain generate artifacts that degrade images quality. Thefore, MRIFre-compatible robotare built fine farely tee teal tee materials and employ specized actio and sensing methods.
