- Reason
- Siemens became aware of a potential safety risk related to the behavior of the 160 MLC when using the "Motion Stop" button followed by "Reset" several times during the treatment of one beam or one segment (issue 1). Additionally, there may be a potential for collision if the operator does not ensure clearance of the extended flat panel positioner for all gantry rotation angles (issue 2).
- Root cause
- Labeling design
- Action
- Siemens sent a Safety Advisory Notice with Update to all affected customers. The notice informed the customers of the risk of pressing the Motion Stop button repeatedly during treatment. Work Steps were provided for customers to follow.
