The unit of measurement of the magnetic field surrounding the periphery of the MR scanner is expressed as:

• A. Tesla
• B. Ohm
• C. Volts
• D. Gauss

Answer: (D)

The magnetic field surrounding the periphery of the MR scanner is measured in Gauss. Gauss is a unit of measurement that quantifies magnetic flux density, specifically, it expresses the strength of a magnetic field. While the more widely recognized unit for stronger magnetic fields is the Tesla, which is equivalent to 10,000 Gauss, Gauss is often used for expressing weaker fields, such as those found around MRI scanners. In the context of MRI, understanding the magnetic field strength is crucial, as it influences the overall imaging capabilities and the quality of the images produced. MRI machines typically operate with main magnetic fields quantified in Tesla, but the surrounding magnetic field, particularly at the periphery, can be more conveniently expressed in Gauss, thus making it a relevant and practical unit for this context.
