Under very specific circumstances, there is the potential for large objects with fine resolution to be displayed cropped when imported from smartbrush into brainlab brain metastases1.0.0 or adaptive hybrid surgery analysis 1.0.0 for the brain metastases 1.0.0, if the cropped object is not recognised by the user before the plan is used for treatment and the deviation exceeds clinically acceptable limits, this could result in ineffective radiation treatment, serious patient injury, or even death of the patient. structures that are cropped in brain metastases are also cropped in the exported dicom rt structure set files. for the adaptive hybrid surgery analysis 1.0.0, if determination regarding the potential for radiotherapy is made, the incorrect information displayed can have an effect on clinical decisions. if the determination is done during surgery this could even, in a worst case scenario, mislead the user in regards to assessing the extent of resection during this surgery.

Brainlab will provide a software update with this issue solved to affected customers. Brainlab will actively contact affected customers starting February 2016 to schedule the update. In the interim, users are advised to implement the following workarounds: After import always carefully review and verify all objects for correctness and validity. Always verify the correct shape of the objects in Brain Metastases or Adaptive Hybrid Surgery Analysis software. If possible do not use image data sets with large slice distance and/or with a low amount of slices. To retrospectively identify if cropped objects have been used for treatment planning, the object contours of a specific treatment plan can be reviewed in Brainlab Dose Review, where the error will also be visible. This action has been closed-out on 26/08/2016.
