Project Description

Objective Approach and Plan Progress and Next Steps
  • Plus toolkit provides access to numerous hardware devices (imaging devices, tracking devices, navigations systems, sensors, etc.) and makes it available through OpenIGTLink protocol
  • Create a common library, OpenIGTLinkIO that makes communication with Plus (and OpenIGTLink-compatible devices or software) very simple:
    • Ensure software interoperability
    • Share software maintenance workload
    • Make it easy to share new features
  • Add specific features for tracked ultrasound and and augmented reality in surgical navigation
  • Improve message header sent by Plus Toolkit for US machines(Ole Vegar, Simon)
  • Build a complete US session simulation (OpenIGTLinkIO motifs, Plus config, Automated tests) (Ole Vega, Simon)
  • Add missing functionality in OpenIGTLinkIO to complete reintegration in OpenIGTLinkIF (Simon, Longquan )
  • Improve support to launch Plus server remotely (Csaba + Andras)
  • Adapt OpenIGTLinkIO to handle video compression functionality added to OpenIGTLink (Etienne + Longquan + Adam)
  • Progress in OpenIGTLinkIO (changes in branch on SINTEF's fork of OpenIGTLinkIO )
    • Simplified handling of command messages in OpenIGTLinkIO.
    • US parameters are now in the header of each image header.
  • Created a US simulation session where 2 parameters (depth and frequency) of the US machine can be remotely controlled. (TODO: put file here)
  • Added support for video streaming (including compression) in OpenIGTLinkIO (Lonquan, remotely). Changes are in Longquan's fork master branch.
  • Remote change of ultrasound parameters. Topic branch:
    • New command to Plus called vtkPlusSetUsParameterCommand
    • Received command is propagated to the ultrasound device and parameter change is requested
    • Example command syntax: <Command Name="SetFrequencyMhz" ParameterDoubleValue="4" /> (Parameter argument not final)
  • Next step
    • Polish code and merge SINTEF's and Longquan's master branch for OpenIGTLinkIO and Csaba's topic branch in Plus.
    • Add support (both in Plus and OpenIGTLinkIO) for automatic probing of US machine capabilities and settable parameters.
    • Finish the work on remote Plus server launch.
    • Build an auto-populated GUI to control US machine in OpenIGTLinkIO. GUI is populated according to parameters recovered from probing US machine remotely
