Manufacturer Reason
for Recall
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.
