A significant limiting factor for electronic devices within the scanner room is the electromagnetic interference (EMI) that they generate. Also, electromagnetic radiation from the scanner can interfere with the safe operation of electronics in close proximity to the scanner. We describe the development of an approach that enables researchers to fabricate inexpensive and reliable shielded enclosures without access to extensive engineering facilities. Our investigation explores the relative advantages and disadvantages in the design and construction of three different shielded enclosures and concludes with a performance evaluation by measuring the frequency dependent attenuation of electromagnetic signal intensity.
