Objective

The objective of this break out session is discuss 1) the current Slicer activities related to ultrasound guided therapies, 2) identify shared interest effort overlap, and common unmet needs, 3) produce common statement from participants about the action plans. Everyone is welcome to attend.

Time/Date/Place

  • In 2012 NA-MIC all hands meeting
  • 8:10-12:00, Wednesday, January 11, 2012
  • Amethyst room, Marriott, Salt Lake City, UT

Coordinator

  • Nobuhiko Hata, PhD, Brigham and Women's Hospital
  • Andras Lasso, PhD, Queens University

Agenda

  • 8:10-8:20, Welcome, Goal of the meeting, Meeting logistics, Note taking in wiki
  • 8:20-8:35, Project introduction 1, PLUS library and/or Canadian projects efforts, Andras Lasso (slides)
    • Keywords: Plus framework, applications, spatial & temporal calibration, volume reconstruction, ECG
  • Project introduction 2, Tamas Ungi, Tracked real-time 2D ultrasound in Slicer (LiveUltrasound).
    • Keywords: OpenIGTLink, needle guidance
  • Project introduction 5, Mehdi Moradi, Prostate 3D US, BWH Efforts on US imaging. The ProFocus BK machine, equipped with the optional research interface has the ability to stream RF data over a CameraLink connection to a frame grabber. This setup is now in use in BWH. The software developed for data logging lacks a GUI, the ability for real time B-mode display, and tracking at the moment. The PLUS library, developed for streaming data from the Ultrasonix machine through an OpenIGTLink, essentially meets the visualization and tracking aims. We want to integrate the BK RF streaming module with the PLUS/Slicer development.
  • short break
  • Project introduction 3, Elvis Chen, GPU volume rendering. We have developed (clean room implementation) a stand-along, CUDA-based, VTK class for volume rendering. It is meant to be a drop-in replacement for vtkVolumeMapper. In addition, we implemented multi-dimentional transfer function, allowing much concise pixel-classification and visualization. Video demo will be given, source code will be made available.

Andras presentation PLUS library Based on Synchrograb Acquire, process, transfer synchronized ultrasound images and position data Specialized Open IGT Link QueensOpenIGTLibs Separate effort from OPEN IGT Link [NH question] any effort toward integration 4D Ultrasound module in NAMIC sandbox repository (*) Features: calibration (*), B-mode imaging capturing (video?) RF?, support for multiple hardware devices Sample data can be incorporated w/o hardware Supported hardware (not defined well, but sounds very attractive to most of the investigators) Standalone solution: Device SDK, and drivers 3D Slicer module Temporal calibration Change detection methods Correlation-based (**) Correct 150 msec File format sequence metafile….. **** we need I/O for this in Slicer, we need module in Slice to handle this kind of data Question… effort to visualize 4D data in Slicer, frames grabbed how does this relates to 4D Volume, or shall we handle this as single frame? 2D+t as primitive needed in Slicer? Logging ---- within library


Tamash

PLUS image acquisition and data transfer to Slicer Open IGT Link send cords of needle and image 2D image primitive with vtkImage updated images are thrown away

What is needed Tracker-model registration module, OR IGT transformation module Time Recording / replay functions Mehdi Moradi Prostate cancer Elastography. Not so much in Slicer. Good platform for translational research Technical issue
