On April 8, 2026 URGENT FIELD SAFETY NOTICE letters were sent to customers. Customers were informed of implementing an updated recurring maintenance inspection for detecting loosened, missing, or broken bolts within the VTA. Hologic Service will reach out to schedule your service appointment and perform the required inspection. Following the initial inspection, recurring inspections are required to be conducted at least every 6 months to ensure continued safe/proper operation of the system. Future inspections will consist of torque and visual confirmation that all bolts are present and that there is no indication of loosening.

If at any time during system operation, you observe unexpected C-Arm movement, please discontinue use and contact Hologic s Technical Support immediately. Report suspected device complaints and/or adverse events to Hologic and the FDA (contact details below). After initial inspection by Hologic, it is required to have the inspection performed at least every 6 months as well as the other defined maintenance and service activities which are critical for continued safe and effective operation of the Selenia Dimensions or 3Dimensions system.
