Technical Information

about the Integration of Synchrograb into Slicer

3D CUDA

TO DO

• Understand the CUDA source code of Nicholas and Ben

Contacts

• Ben Grauer: Volume Rendering with CUDA
• Nicholas Harlambang: CUDA Guru

Documentation: VolumeRenderingCuda Module

• Adjust the threshold (scroll bar below 'Component Weights Scrollbars') to correct values. Especially the lower value. Normally > 0
• Scalar Opacity Mapping: Shows a histogram of the used values an their transparence. Low transparent, high solid
• Scalar Color Mapping: You can click into and than in the color circle above and select certain colors for a specific value
• Composite: Here you can select different rendering modes
• Volume: You can also select just to display a slice instead of the whole volume. You can transform the slice in the Transforms Module and than select the transformation matrix in Slice Matrix
• Plus/Minus: Select if you want to see everything or just the volume on one side of the slice and on the other

Ultrasound tracking device

Hopefully most of this part is already done by SynchroGrab

SynchroGrab

In summary SynchroGrab does:

• Continuous acquisition of ultrasound images using an open-interface ultrasound system;
• Continuous acquisition of tracking information using a pose measurement system;
• Explicit synchronization of the two acquisition threads;
• Reconstruction of 3D ultrasound volumes using the synchronized data; and
• Transfer of the raw ultrasound images, the 3D volumes and the probe tracking information to an OpenIGTLink-compliant system.

TO DO

• Find out what is already coverd by Synchrograb
  • Adjust the tracker part, so that our tracker is working
  • Replace image acquistion part. We have to use a frame grabber card instead of reading the images directly from memory
• Compile Synchrograb and see if everthing is working

Capture Video

• Existing Videocard: Hauppauge ImpactVCB [1]
• Linux Driver: Video4Linux2
  • There is existing C source for V4L2 on the web
  • Should run on new fedora kernel

Calibration

Description: To get correct information from the ultrasound device it has to be calibrated
