Twenty three investigators using Slicer for their IGT research supported by NIH gathered in Brigham and Women's Hospital from December 12 to 14, 2007.
 +
We discussed current status, unmet needs, future direction, and resource sharing in Slicer engineering. Four live demonstrations using real tracking device
 +
and phantoms were performed to facilitate the discussion.  In summery, we concluded that the 3D Slicer, which currently centers around medical image
 +
processing and visualization,  definitely has proven to be also useful for IGT and has potential to become enabling tool for new domain of research in IGT.
 +
However, we also agreed that Slier still has gap in its in feature list to meet requirements of the investigators goals in their own clinical targets as well as innovative IGT applications.  These unmet needs are
 +
*Plug-in mechanism to develop a high-performance software specifically tailored to a target clinical application
 +
*Controlled and fast Data/communication/event management
 +
*Inter-device communication mechanism to/from Slicer
 +
*Fast Volume rendering for 4D IGT
 +
*Flexible GUI design
 +
Objective evidence for existence of these needs derives from our own assessment as well as our extensive discussion during the meeting. Continued existence of these need represents an important problem because, until the needs are met, new and innovative IGT procedures using state-of-art imaging and treatment device may not be available due to lack of guiding and navigation software.
 +
As the next step in IGT research using Slicer, we decided to collaboratively develop the above mentioned mechanism through resource sharing, frequent communication, and if necessary additional funding support.

Introduction

This was a working meeting for research groups with funding to work on the IGT extensions of the NA-MIC kit. There will be a follow up meeting during the NA-MIC AHM in SLC.

Summery

Over 20 researchers attended this meeting.

Goal

  • Continued discussion of Slicer IGT infrastructure, applications, and timelines
  • Introduce each team's effort in Slicer in the context of IGT
  • Find unmet needs
  • Identify high-priority working items
  • Identify each team's potential contribution to the high-priority tasks

Meeting summery

Twenty three investigators using Slicer for their IGT research supported by NIH gathered in Brigham and Women's Hospital from December 12 to 14, 2007. We discussed current status, unmet needs, future direction, and resource sharing in Slicer engineering. Four live demonstrations using real tracking device and phantoms were performed to facilitate the discussion. In summery, we concluded that the 3D Slicer, which currently centers around medical image processing and visualization, definitely has proven to be also useful for IGT and has potential to become enabling tool for new domain of research in IGT. However, we also agreed that Slier still has gap in its in feature list to meet requirements of the investigators goals in their own clinical targets as well as innovative IGT applications. These unmet needs are

  • Plug-in mechanism to develop a high-performance software specifically tailored to a target clinical application
  • Controlled and fast Data/communication/event management
  • Inter-device communication mechanism to/from Slicer
  • Fast Volume rendering for 4D IGT
  • Flexible GUI design

Objective evidence for existence of these needs derives from our own assessment as well as our extensive discussion during the meeting. Continued existence of these need represents an important problem because, until the needs are met, new and innovative IGT procedures using state-of-art imaging and treatment device may not be available due to lack of guiding and navigation software. As the next step in IGT research using Slicer, we decided to collaboratively develop the above mentioned mechanism through resource sharing, frequent communication, and if necessary additional funding support.

Agenda

Wednesday, December 12

Theme: Where are we?

12noon: Lunch

12:55pm: Welcome (Ron Kikinis)

1-2pm:Slicer and IGSTK presentation

  • Slicer: overview of architecture, current status, and future plans (Pieper, Hata)
  • IGSTK
    • Architecture Overview (Ibanez)
    • Current status, and future plans (Cheng) Refactoring Design Discussion
    • IGSTK has time stamping for tracker and event.
    • Monitors to ensure the minimal latency between display and data acquisition (possible take away from IGSTK to Slicer).
    • GUI tools for sample programs are FLTK and Qt

215-330pm: Presentation by Slicer Developers

  1. Move toward multi-process model, keep idea of GPU capability in mind for future
  2. online/unsupervised segmentation, online/fast registration (almost like tracking); can trade some accuracy for speed
  3. flexibility in registration techniques - data collection is not perfectly constrained (patient positions vary, image quality varies, fiducials sometimes/not) - tools for anatomy-based registration
  • 3:00-3:15 - NA-MIC Collaborator Georgetown Cleary/Yaniv
  • 3:15-3:30 - NA-MIC DBP Queens/JHU Gobbi/Csoma/Kazanzides
  • 3:30pm-3:45pm: Review of today's progress

400pm: Adjourn

4-6pm (optional) MRI Demonstration

  • Use of Slicer for control and display with MRI (prostate module) presented by Junichi Tokuda. Location: Advanced MRI center, 221 Longwood, Boston

Thursday, December 13

Theme: Where are we?

9-10:00am Demos:

  • Hata (Tracking at BWH)
  • Freudling (Pieper) (Volume rendering)

1000-10:30am Demonstrations

    • Robot-assisted neurosurgery with Slicer (Kazanzides)
    • Robot connected to Slicer via Robot control unit (with Real time OS)
    • Slicer CT coords != Stealthstation CT coords
    • Needs rasToIjk matrix from xml file
    • Inter-computer communication
  • Slicer 3 IGT update

10:30am: Identifying the unmet needs

(At this point, representatives from each site should start thinking which part of the unment needs they can take primary responsibility, and take home as homework.)

  1. Queens: NA-MIC DBP
  2. JHU: BRP
  3. BWH: NCIGT etc.
  4. Georgetown: Liver RF
  5. Kitware-BWH
  • Identify the unique needs in IGT
  • Identify commonality among the projects
  • which one is to be covered by actively funded project?
  • Identity and prioritize unmet needs
  • Find commonality among the needs, consolidate if necessary
