Which coils are closest to the patient in a cross-sectional view of the MR magnet design?

  1. Gradient coils

  2. RF coils

  3. Shimming coils

  4. Passive coils

The correct answer is: RF coils

The RF coils, or Radiofrequency coils, are located closest to the patient in the design of an MRI system. These coils play a crucial role in the imaging process by transmitting radiofrequency pulses to excite the hydrogen protons in the patient's body and subsequently receiving the signals emitted during the relaxation process. Their proximity to the patient enhances signal reception, allowing for clearer and more detailed images. The presence of RF coils near the patient is vital because the strength and quality of the received signals can greatly affect the image resolution. Given their active role in both sending and receiving signals during the MRI scan, it’s essential that RF coils are situated as close as possible to the area of interest being imaged.
