MR Safety

BOLDscreen is categorised as MR safe in accordance with the labelling requirements of ASTM F2503-08 (“an item that poses no known hazards in all MR environments”). See FAQs.

The power supply and cables are MR conditional (“an item that has been demonstrated to pose no known hazards in a specified MR environment with specified conditions of use”).

EMC

BOLDscreen has no observed effect on functional and structural MRI scans at 3T, even with screen located at exit of scanner bore, and no effect on displayed image whilst scanning. See test data.
