In the context of MRI (Magnetic Resonance Imaging) systems, the unit of magnetism is a crucial aspect to understand since it determines the strength of the magnetic field used in imaging.
In MRI systems, the measure of magnetic field strength is typically gauged in specific units associated with magnetism. Let's review the options provided:
1. Decagrams/Kilograms: These are units of mass, not related to magnetism.
2. Gauss/Tesla: These are indeed units of magnetic field strength. The Tesla is the SI unit for magnetic flux density, commonly used in MRI systems. One Tesla (T) is equal to 10,000 Gauss (G). Therefore, MRI systems often describe magnetic field strengths in Teslas or Gauss.
3. Volts/Kilovolts: These are units of electric potential or voltage, unrelated to magnetism.
4. Rems/Rads: These units measure radiation dosage, not magnetic field strength.
Given these options, the unit of magnetism for an MRI system is correctly measured in Gauss or Tesla. Thus, the correct answer is:
Gauss/Tesla
