Istra Corporation manufactures relocatable Faraday cages and RF shielding systems for MRI rooms, using prefabricated aluminum panels that can be assembled on site without cutting or welding. Its water-resilient designs are built to avoid warping and RF leaks caused by flooding or humidity, while the perforated shielding cage gives patients an open, see-through environment during scans. The Cleveland-based company also provides customized luminous ceilings and flexible magnetic shielding for MRI facilities.
