Patient images exhibited ring artifacts.

The firm, Philips Healthcare, sent an "URGENT - Medical Device Correction" letter dated December 9, 2013 to their customers. The letter described the product, problem and actions to be taken. The customers were instructed to do the following to avoid the occurrence of these specific ring artifacts: 1. Disable Automatic Scan Time for all Exam Cards 2. Leave Automatic Scan Time on during planning and prior to clicking Go to initiate the scan, click the acquisition series of the scan and disable Automatic Scan Time, then proceed with the scan. 3. Disable Edit Before Final Recon (Reconstruction) for all Exam Cards If a ring artifact is present, clinical judgment should be used by the customer/user to determine if the images acquired in the dataset contain enough information to make a diagnosis. Philips will be releasing a Field Change Order (FCO) to correct the issue with software version release 4.1.1.19261. In addition, a Philips Field Service Engineer will contact you to schedule the software installation at your site.
