Manufacturer Reason
for Recall
There is a potential that Wedge IDs were not included in the DICOM RT PLAN sent from the TPS, which will cause the field in MOSAIQ to be created with no wedge. Treatment of a field without the planned wedge will receive more dose than the treatment plan indicates.
FDA Determined
Cause 2

Action Elekta sent a letter to affected customers titled, Urgent Field Safety Notification, on about 12/13/2018. The letter contained recommended user action to review the TPS system to verify that Wedge IDs are defined for all wedges and check to make sure that the exported RT Plan information contains the necessary Wedge IDs. Instructions also included to post the recall notice in a place accessible to all users until the correction is closed, and to advise the appropriate personnel working with the affected product of the recall. The letter stated that the issue will be resolved in MOSAIQ Release 2.80 Beta 01. The update will be provided in Service Packs to MOSAIQ and Multi-ACCESS who will be notified with a Product Bulletin when the Service Packs are available.
