What’s new Support for new hardware: brachy stepper, EM tracker, new Ultrasonix SDK versions, … New applications: calibration, volume reconstruction, diagnostics, … Enhancements: temporal calibration – a.k.a. synchronization, … Bugfixes Automatic tests But: Some old hardware and applications are not tested or not integrated. Tested on Windows only Laboratory for Percutaneous Surgery (The Perk Lab) – Copyright © Queen’s University, 2011

Software platform Language: C++ Build system: CMake Automatic testing and dashboard: CTest, CDash External libraries: – Required: ITK, VTK – Optional: OpenIGTLink (for communication with 3D Slicer and IGSTK), device drivers Supported operating systems: – Windows XP (32-bit), Windows 7 (64- bit): regularly tested – Linux: not tested, everything should work except Windows drivers and RS- 232 serial communication PLUS library VTKITK Open IGTLink SDKs and drivers Applications (PLUS applications or custom apps) - 5 -Laboratory for Percutaneous Surgery (The Perk Lab) – Copyright © Queen’s University, 2011
