Siemens became aware of a potential safety issue when using the “IMMEDIATE RESUMPTION” feature of the syngo RT Therapist 4.2 software after a Control Console interlock during the delivery of flattening-filter-free (Multiple-X) beams or segments; in a very rare scenario, the RT Therapist will send again the previously completed beam or segment for delivery to the control console, thus repeating the already delivered Monitor Units of the same beam or segment.
