- Reason
- Incorrect Software Validation- The ARC treatment plans containing a Dose Dynamic MLC for IMRT delivery that will not be recognized properly by the system. Under these circumstances, an arc plan can be administered to a patient whereby the gantry will not rotate, resulting in delivery to a single location rather than through the gantry arc.
- Root cause
- Software design
- Action
- An Urgent Medical Device Correction letter was distributed October 2, 2007, to all direct consignees, informing them that the ARC treatment plans containing a Dose Dynamic MLC for IMRT delivery will not be recognized properly by the System. The firm provided corrective instructions and informed consignees that a product modification will be developed to resolve the issue. A Varian Service Representative will be scheduling a visit to upgrade the application.
