Varian Multileaf Collimator [MLC] recall: Software Issue
Varian Multileaf Collimator [MLC]; Millenium Multileaf Collimator [52, 80, 120 leaf]; High Definition 120 Multileaf Collimator Model Number(s)…
Why was Varian Multileaf Collimator [MLC] recalled?
After a recent upgrade to the collimator software version 8.5, the firm became aware that the multi-leaf collimator leaves did not move during an arc treatment. The issue is related to a transient carriage primary- secondary interlock due to carriage fault on the MLC that immediately preceded the initiation of the arc treatment. The issue will occur only with MLC software version 8.5 and only affects conformal arc treatments, including VMAT and RapidArc. There have been no reports of adverse health consequences due to this issue.
