2012 Summer Project Week Breakout Session:Ultrasound

Back to agenda

Objective

We discuss how to use 3D Slicer in ultrasound (US)-guided interventions. Our goal is to identify common functions in these applications and create a platform from them in 3D Slicer.

Time/Date/Place

• In 2012 Slicer programming week
• 1pm - 3pm, Thursday, June 21, 2012
• Grier, MIT

Coordinator

• Tamas Ungi, Queen's University
• Kirby Vosburgh, BWH

Agenda (tentative)

• Temporal and spatial calibration of tracked US probes using PLUS (Csaba) (slides)
• Real time US display in Slicer to guide interventions (Tamas)
• Perk Tutor: A configurable, Slicer-based training platform for ultrasound-guided needle insertions (Tamas)
• Low cost hardware. Capture and replay of experimental or clinical sessions (Kirby)
• Slicer CaseHub - Plans for capturing, organizing, and accessing multi-track procedure data (Steve)
• US to US registration (Matt)
• 4D US in Slicer (Laurent)
• Transapical valve surgery - not yet in Slicer (Elvis)

Topic suggestions

1. Improving Ultrasound imaging. This involves acquiring RF level or other data from the mid-processor stage of the imager (see http://www.ti.com/lit/wp/sprab12/sprab12.pdf, Figure 2) with the intent to provide a more suitable image for a particular application.
2. Ultrasound post-processing, in which the image is processed to better enable, for example, registration to a CT data set.
   1. Denoising with Ultrasound specific statistical filters
3. Calibration, registration and display of ultrasound in 3D Slicer
4. Real time (lag free) display of high quality US in Slicer for procedure guidance and lag free registered display in 3D models.
5. The combination of 3 and 4 on low cost commodity hardware.
6. The capture of all data to enable post procedure replay of a experimental or clinical session, so that the various processing steps can be debugged and optimized.
