MRSO - Static Field - Module 2 questions well answered 2024/2025

MRSO - Static Field - Module 2Static field metrics - correct answer 1T = 10,000G (0.5mT = 5G) Who published guidelines titled "Criteria for Significant Risk" that specifies what qualifies as significant risk of exposure to magnetic field associated with MRI. - correct answer FDA FDA guidelines state EXPOSURE to a static field that does not pose a significant risk is: - correct answer Limited to 8T for adults and infants > 1 month Limited to 4T for infants < 1 month Forces related to static field - correct answer -Torque/rotation -Translation/Displacement -Lenz magnetic saturation - correct answer The point where an increase in magnetic force produces no further magnetic effect in a magnetic material. . magnetic saturation depends on: - correct answer -material -size and shape -temperature Most ferromagnetic items are going to saturate at: - correct answer 0.3T - 2.2T Torque - correct answer force exerted on elongated ferromagnetic object so it aligns with the direction of the magnetic field
