Action The firm, RaySearch Laboratories, sent an email with an "Urgent Field Safety Notice Medical Device Correction" notice dated October 19, 2011 to its customers. The notice describes the product, problem and actions to be taken. The customers were instructed to pass on the information in the field safety notice to everyone involved and create routines to compensate for the incorrect DRR images; if the DICOM DRR images are not used to make any form of absolute measurements, no action needs to be taken. Raysearch laboratories will provide a script to update these DICOM files to have the correct values upon request.
