Potential safety issue under specific preconditons that may result in a user selecting the wrong site for treatment with the possibility to deliver dose to the wrong isocenter which could result in serious patient injury

Siemens issued Urgent Medical Device Corrction Letter CSAN TH001/21/S on 12/09/2021 to inform them of the potential issue and associated risk. Acton to take: 1. Carefully verify all planned treatment parameters against those actually set during patient setup before treating a patient. 2. Choose one of the following workflow options: - Use absolute table positions. In this case, positioning on a different isocenter would not match the planned table values and the system would prompt an override request. This minimizes the risk of selecting a wrong site fraction group. Or - In the case of mulitple sites, select and download one site at a time from ARIA. In this case, RTT would only display one site. Or - Create a multiple isocenter plan in ARIA. RTT cross checks table positions and selected isocenter coordinates. Siemens also recommends consulting the your system s Instructions for Use, Chapter 3.3.4, One treatment plan divided into two plans . The workflow described in this section prevents the occurrence of the reported incident. Please review, understand, and confirm acknowledgement of the information and instructions outlined in this Urgent Safety Advisory Notice.
