Potential safety issue with the dose monitoring system safety interlocks which could result in a 10-20% overdose of radiation therapy.
Siemens Medical is recalling specific ONCOR radiation therapy devices that may cause a 10-20% overdose of radiation therapy due to a problem with the dose monitoring system safety interlocks. This could lead to unnecessary radiation exposure for patients during treatment.
The dose monitoring system safety interlocks in these devices could malfunction, potentially allowing radiation therapy to exceed safe levels by 10-20%. This risk occurs during treatment when the device is operating normally.
Patients receiving radiation therapy using the recalled ONCOR devices are most at risk. Healthcare facilities that use these specific models for treatment may also be affected.
Check if your device has the model names listed: ONCOR Avante Garde, Expression, Impression, or Impression Plus. Look for specific software versions 6, 7, 9, or 13 and the listed serial numbers in the recall notice.
