Under certain circumstances, it can occur that patient records from unrelated individuals are automatically merged into one patient record without user notification.

Risk of mechanical instability due to potential manufacturing error of the device

Deep Inspiration Breath Hold (DIBH) functionality may not work as specified when based on a standard-workflow Treatment Template

The yaw angle may be incorrect for CBCT positioning workflows using setup beams with Varian LINACs.

Display of potential patient movement might be delayed to the user for high dose treatments.

In case of a failed automatic marker detection, a software error causes parts of the display to incorrectly behave as if the current patient position is within predefined tolerances and may allow the user to proceed to treatment despite potentially exceeding shift values.

Brainlab Ultrasound Navigation Software does not support the modification of the probe's image width.

Holding force of the Positioning Arm can be reduced by prolonged non-use.

The Brainlab Patient Data Manager software (PDM) in combination with the Brainlab iPlan CMF/Cranial/ENT/Spine software 2.1.1, 2.2.0, 2.2.1, 2.3.0, 2.3.1, 2.4.0, 2.5.0, 2.5.1 (if used in combination with iPlan CMF/Cranial/ENT/Spine 3.0.5, 3.0.6) that may lead to shifts applied to segmentation objects in iPlan being not reflected when exported into DICOM under specific circumstances.

There is a potential for an incorrect dose distribution calculation by Brainlab RT Elements software (for affected versions) under specific circumstances when using the Pencil Beam algorithm on the GPU (graphics card), as is the default system setting.

In certain occurrences, the affected navigation software application might unexpectedly display a navigated instrument in an axial, coronal/sagittal (ACS) view representation with fixed planes in the image reconstruction (the not-updated ACS view ), instead of displaying the desirable view representation Inline View , which is commonly used for navigating invasive instruments at the spine. This could lead the surgeon to be unable to determine the position of the navigated instrument. This might occur after a crash restore or after changing between different navigation workflows during the same patient treatment.

The usage of workflows that deviate from the recommended specifications in the User manual for ExacTrac Patient Positioning System (versions 6.0, 6.1, 6.2, 6.5) with Auxiliary Device Interface (ADI) and Varian Clinac or Varian TrueBeam, which may result in misinterpretation of beam authorization via ADI.

Risk of unintended motion while the AIRO system is in transport mode.

Due to a human error at a supplier, an unknown number of devices within one specific production lot of Brainlab DrapeLink Adapters (Left/Right) were not manufactured according to defined specifications.

Brainlab has internally detected that under specific conditions ExacTrac Vero may not correctly account for this ring angle correction during the calculation of the corresponding couch shift. This may result in the treatment couch not moving to the exact planned position resulting in a deviation between the planned and the treatment target position. This deviation may not be clearly visible to the user if no verification image of the patient position is acquired after this couch shift has been performed.

Brainlab Knee Navigation System: Femoral and Tibial Cutting Block Adapter Base with specific serial numbers might contain parts made from incorrect material and therefore not be suitable for reprocessing

Potentially incorrect positioning when using Implanted Marker Detection with Brainlab ExacTrac Vero 3.5

Software Error: The effect of setup on overall navigation accuracy could potentially intensify small inaccuracies arising from individual steps of a complex navigation procedure that may cause an inaccurate display of instruments by the navigation system compared to the actual patient anatomy.

Large objects with fine resolution are potentially displayed cropped when imported into Adaptive Hybrid Surgery Analysis version 1.0.0

Large objects with fine resolution are potentially displayed cropped when imported into Brainlab Brain Metastases 1.0.0.

Instances of data sets not being accurately registered to the patient anatomy were observed.

Potentially incorrectly displayed objects when actively deselecting a fused reference dataset.

Disposable Reflective Marker Spheres (DRMS) for Brainlab Image Guided Surgery (IGS) Systems: DRMS spheres may separate at the mid-point where the two halves of the sphere are sealed together.

ExacTrac 6.0 Patient Positioning System: Display of potentially incorrect Digitally Reconstructed Radiograph (DRR) for x-ray correction and verification.

ExacTrac 6.x Patient Positioning System: Potentially incorrect patient positioning when using the ExacTrac Cone Beam CT (CBCT) with a CBCT acquired at a couch angle other than 0.0 degrees.

The ExacTrac 6.x Patient Positioning System may incorrectly position the patient when using the ExacTrac Cone Beam CT (CBCT) with a TrueBeam-specific optional subvolume-CBCT.

The recommended sterilization and drying parameters are not effective to achieve the minimum required sterilization level.

iPlan RT Radiation Treatment Planning Software: Potentially incorrect patient positioning when using multiple localized CT image data sets.

Brainlab Navigation Software Spine & Trauma 3D 2.0/2.1 offers automatic registration of intraoperatively acquired CT image data sets. To enable automatic registration, the software requires the gantry position of the scanner. The gantry position can either be entered manually or submitted automatically from the CT scanner. If automatic gantry communication is available, the so-called &quot

When using multiple isocenters (radiation treatment targets) within a single plan, in certain workflow conditions ExacTrac v.6.0.4 might move the patient to an unintended isocenter position, despite displaying the green "OK" icon. If this anomaly occurs and is not detected by the user, the radiation treatment dose at the linear accelerator may be delivered to the unintended target position.

The following defects have been identified for data loaded with Patient Data Manager version 2.0 (including subversions 2.0.0, 2.0.1 and 2.0.2): 1) When loading non-square pixel image data with PDM 2.0, the data set is not correctly transferred and displayed in the corresponding Brainlab navigation or planning software. When a data set is loaded, the pixels of the data set are sorted in order to

When using a specific plan update workflow in combination with a non-Brainlab treatment planning system (TPS), there is a possibility in ExacTrac 5.5.5 to generate an unintended blend of two initially separate plans of the same patient.

When using multiple radiation treatment targets within a single plan, the ExacTrac v.6.0.3 might position the patient to an unintended radiation treatment point. As a result, there is a possibility that the radiation treatment dose may be delivered to the unintended target position.

The "fluoro match registration" function of the Navigation Software Spine & Trauma 3D 2.0 allows the user to intraoperatively match e.g., CT data sets to the current patient anatomy visible on fluoroscopic images, used by the navigation software during spinal surgeries to display the position and orientation of instruments. For this registration function in combination with a digitally integrated

Brainlab has determined that pins of thee Instrument Star Unit ML (Calibration with ICM4) with specific serial numbers might have been made of an incorrect material that is not suitable for the necessary disinfection and sterilization of the product. If corrosion occurs and is not detected by the user, and the device is used during surgery, corroded particles of the pin could, directly or indirect
