- Reason
- XiO Software: when a treatment machine is defined in Source File Maintenance (SFM), the MLC Model is set to Elekta, and beams using this treatment machine are added to a new plan in Teletherapy, XiO automatically adds an MLC to the beam. This is because the Elekta linac will always have an MLC in place when the plan is actually delivered.
- Root cause
- Software design
- Action
- A Safety Notice, dated 5/20/10, was sent to Elekta / Computerized Medical Systems Inc clients in May 2010. The notice indicates the problem, the clinical impact.

The notice also informed the consignees they would be contacted when a solution was available.
