### 4. Description of device:
FHC, Inc. STarFix™ Designer software is an advanced image-based neurosurgical planning software application designed for generating patient specific frames (FHC, Platform) primarily for Deep Brain Stimulation (DBS) Proedures and stereo-electroencephalography (SEEG) by means of the WayPoint™ Stereotactic platforms.
The STarFix™ Designer offers the following core features:
- Image import and registration
- Open and manipulate CT and MR images for surgical planning
- . Rigid registration between CT and MR images, with user-selected reference scan of either modality.

- Automatic localizer extraction
- Extract localizers from preoperative CT manually or automatically
- I Manually place localizers on MR scans
- Manual refinement of localizer position
- Patient specific 2D and 3D visualization of anatomical landmarks: AC, PC, MP
- Trajectory planning ●

- DBS STarFix™ Platform frame modeling ●
- . Multi-Oblique STarFix™ Platform frame modeling
- . Export and import planning data, including images, for transfer on another computer or to be saved for easy reference during the surgery
- Save the plan any time during the planning session
The STarFix™ Designer provides a modern design, built to ease user interaction, and allow fast and efficient planning for the WayPoint™ Platforms and ultimately, the implantation of DBS electrodes. With safety as a primary concern, all planning elements need to be verified and marked explicitly before a platform model can be built. The user interface is guiding the necessary planning steps, by using numbered menus and intuitive labeling, along with a minimum of application settings and common actions arranged in the form of a toolbar dedicated to either 2D or 3D operations.
Image /page/4/Figure/13 description: The image shows a medical imaging interface with multiple views of a brain scan. The interface is divided into sections for imaging, fiducials, anatomy, trajectories, and platform. The brain scans are displayed in 2D and 3D views, with green lines indicating trajectories or points of interest. The display orientation is set to 'Original' with L: 2.75, P: 0.82, and S: -1.93.
