IV2
IV2 is a comprehensive surgical navigation system for ENT surgery. Using advanced technology and a high-precision CCD camera in the visible spectrum, it provides more accurate and reliable navigation during surgery.
Key Features
- Standalone planning station with full capabilities
- Compact design with high maneuverability
- Easy positioning of the surgeon's dedicated display
- Wide surgical coverage with long adjustable arms
Applications
ENT Applications
Like skull surgeries, ENT procedures require high precision to navigate very narrow pathways and cavities in this region. The navigation system in ENT can be used for:
- Sinus surgery
- Cyst and polyp removal
- Optic nerve decompression
Specifications

- Support for DICOM datasets including CT, MR, and PET
- Import from CD, DVD, and memory stick
- Review dataset tree structure
- Preview image data before loading
- Correct patient demographics that may be incorrectly recorded in DICOM images
- Automatic detection of dataset issues
- Automatic compatibility check for navigation requirements
- Determine medical image orientation from DICOM headers
- Correct image data orientation
- Add a new dataset to a patient record intraoperatively
Visualization
- Easy imaging tools: zoom, rotate, and pan
- Window level, transparency, color coding, and related adjustments
