2012 Summer Project Week:BK-PLUS Integration

• 

  Projects List

• 

  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.
