• Recalling Firm/ Manufacturer: Elekta Limited; Linac House; Fleming Way; Crawley United Kingdom
• Manufacturer Reason for Recall: In TSM (Treatment Session Manager) Motion Monitoring workflows, under certain conditions there can be a mismatch between the contour data overlay with respect to the motion monitoring images of the monitored structure.
• FDA Determined Cause: Device Design
• Action: Elekta notified customers of the recalls on about 05/21/2020 via "URGENT IMPORTANT FIELD SAFETY NOTIFICATION" letter. Customers were informed that in TSM (Treatment Session Manager) Motion Monitoring workflows, under certain conditions there can be a mismatch between the contour data overlay with respect to the motion monitoring images of the monitored structure. Instructions included that although there is no method to correct the scaling issue for the affected protocols, the device can still be used under two options: 1. Without the use of Motion Monitoring and 2. compensation for intra-fraction motion can be done through the acquisition of a 3D Verification MRI, which is not impacted by the scaling issue. On 08/05/2020, Elekta issued an additional customer notification to provide additional details of the recall status and to clarify and provide a more generic message regarding the recall issue.
