Target Alignment Error : A mechanical component/software incompatibility caused by a specific combination of the BrainLAB Target Positioner version 40700-3A for Leksell headrings and BrainLAB planning software resulted in a 1.25 mm shift in target area alignment during radiosurgery treatment.

BrainLAB immediately notified all customers with the BrainSCAN or iPlan RT Dose software in combination with the BrainLAB Target Positioner for Leksell Headring, via e-mail on June 5, 2007. The Urgent Medical Device Product Notification letter dated June 4, 2007 included in the e-mail informed the customers that both the BrainSCAN and iPlan RT Dose treatment planning software calculates the isocenter position printed on the Target Positioner Overlays shifted 1.25 mm in cranial direction from the intended position, when the BrainLAB Target Positioner for Leksell Headring Revision A is used. The customers were instructed to cease using the BrainSCAN or iPlan RT Dose software in combination with the BrainLAB Target Positioner for Leksell Headring for treatment planning and patient set-up. An updated target positioner will be provided to the customers to correct the problem, estimated to be available in September 2007.
