I teach a class in hands-on MRI and today we just happen to be building simple RF receive only coils for the scanner. They'll have to lay out the copper tape in a license plate sized rectangle, and tune them with the proper capacitors to 63.8 MHz. Then they build a blocking network so they don't burn up when they're subjected to the main RF pulses. About half of them have some soldering experience so the end results are sometimes ugly. They always work though, many times better than the factory coils with pretty covers.
