Recall Details

Company:
Ion Beam Applications S.A.
Reason for Recall:
When switching from Pencil Beam Scanning treatment mode to Uniform Scanning treatment mode, the tuning setpoints of the scanning magnets are not always taken into account when the proton beam is requested. The mismatch between the setpoint and feedback leads to an error message. Depending on user action, two scenarios are possible: 1. The user resumes the treatment field without analyzing the cause for the error message. This may lead to under-irradiation. 2. The user reboots the Scanning Magnets Power Supply Electronic Unit. This may lead to delay in patient treatment and the patient may need to be re-aligned, which leads to an additional X-ray dose.
Classification:
Class I - Dangerous

Dangerous or defective products that predictably could cause serious health problems or death.

Status:
