Recalling Firm/ Manufacturer |
Ion Beam Applications S.A. 3 Chemin Du Cyclotron Louvain-la-neuve Belgium

Manufacturer Reason for Recall | First layer of Uniform Scanning treatment fields is sometimes irradiated with incorrect Scanning Magnet setpoints resulting in the field size may be smaller than expected and the irradiated area may receive more dose than prescribed |
FDA Determined Cause 2 | Under Investigation by firm |
Action | ***UPDATE 12/22/22***
Ion Beam Application S.A. (IBA S.A.) issued an Amended Urgent Medical Device Correction to customers starting December 22, 2022 (supersedes previous letter Sept 15, 2022). Letter provides quantitative data about the impact on the dose distribution, and the description of the solution (software upgrade) as well as the time schedule for its deployment.
Cyclic check thresholds verification and software upgrade Additionally, IBA will provide each impacted customer with a report including:
- The list of the Uniform Scanning fields with the first layer entirely delivered with the tuning setpoints and a significant difference (above 0.3V) between the prescribed setpoints and the tuning setpoints,
- The modelled maximum and average dose errors for these fields
IBA will upgrade the PTS version to ensure that:
- the irradiation of a layer cannot be started if the Scanning Magnet setpoints for the layer are not properly sent to the Scanning Magnet Power Supply, and - no setpoints request can be lost (even if previous requests are not yet executed or completed).
The report including the identified impacted Uniform Scanning fields with the modelled maximum and average dose errors for these fields will be provided to each impacted customer by February 28, 2023.
On the sites where IBA has not yet finalized the verification and the possible adaptation of the field size and dose rate cyclic check thresholds, this action will be completed by January 15, 2023.
The PTS version upgrade will be deployed on your site by March 31, 2023.
