BK ProFocus ultrasound scanner
Live ultrasound in 3D Slicer
Key Investigators
- Queen's: Andras Lasso
- BWH: Andriy Fedorov, Isaiah Norton
Objective
Make live ultrasound images acquired by a BK ProFocus scanner in the AMIGO suite at BWH available in 3D Slicer.
Approach, Plan
Create a new video source class in the PLUS toolkit that receives the data from the scanner. PLUS can stream the live data through OpenIGTLink to Slicer.
- Test frame size, decimation, and orientation in vtkBkProFocusVideoSource and PlusBkProFocusReceiver
- Fix image display in vtkBkProFocusVideoSourceTest
- Add user option to record B-mode or RF-mode image
- Tentative: scan conversion from RF-mode (currently only intensities are converted, but the scanlines are not mapped to physical space). Algorithm may be available in Grabbie or could ask Mehdi, or implement a new one.
- Tentative: get displayed image data through the TCP/IP research interface. Need to apply a fix to Grabbie (Isaiah knows the details). Need to extend the BK interface class or create a new one.
- Tentative: perform temporal and spatial calibration with the BK and an Ascension 3DGm in AMIGO (needs B-mode image, either using the TCP/IP interface or a VGA framegrabber)
- Tentative: Try PLUS with the Black Magic Design HD capture card
Progress
New interface class created in PLUS that can receive the RF data and do basic B-mode conversion through a CameraLink framegrabber (any DALSA card with Sapera SDK).
Delivery Mechanism
Integrating new features in PLUS and SlicerIGT extensions.
