Immediate Action Items:

• Ahmet
  • Review contents of subject configuration XML file for in vivo testing.

• Tammy, Tara & Ahmet

  • Meet to conduct mock up session to evaluate in vivo testing protocols.
• Ben
  • Complete documentation of simple indentation model using FEBio.
  • Setup up basic indentation model in Sofa.

• Robb & Tara

  • Update data collection software to add subject ID to pulse train sent to the ultrasound system.
  • Implement calibration and gravity compensation strategies.
  • Incorporate/associate transformation configuration to tdms data file for calibration and weight compensation.

Notes:

1. Discuss immediate action items from past meetings.
   • Ahmet finalized the presentation for in progress review meeting for the US Army. He went over the presentation and described the status of the project to team members.
   • Ahmet needs to review the file structures of the in vivo data collection system in more detail.
   • Tammy learned that foot switches are thrid-party OEM products. She tried a foot switch obtained from the Li Laboratory with the ultrasound system. This loaned switch allowed stopping of the ultrasound image collection automatically, while the other switch (available with the ultrasound system) did not work. This indicated that a different foot switch similar to one used by Li Laboratory should be obtained. We can buy one for ~$150. Tammy noted that the data collection duration with the foot switch was limited to 10 seconds. This may be long enough to get desired data.
   • Tammy uploaded pictures on in vivo experimentation setup and relevant components to the wiki.
   • Ben completed the mesh analysis using the simple indentation model in FEBio. He was able to get similar indenter force-displacement results for hexahedral, linear tetrahedral, and quadratic tetrahedral elements. The solutions with the hexahedral meshes were the fastest ones. He started putting the documentation and models in the source code repository. Ben and Ahmet described the importance of mesh convergence to Eric and the group, to make sure that results do not depend on mesh size and to understand the influence of coarsening the mesh for surgical simulations for simulation speed up.
   • Robb and Tara has been working on the data collection software. A working version with all desired features will be available for the mock up session.
   • Tara reviewed "Setup LINUS" section in the specifications page of in vivo testing.
2. Readiness for in vivo testing.
   • The next mock up session will be on upcoming Friday.
   • Updates on data collection system has been ongoing. A working version of the software with all the features will be available for the upcoming mock up session. Ahmet still needs to review the interface and file structures in more detail.
   • The ultrasound probe - force transducer fixture and handle is ready for the next mock up session. A new cable hook to get the ultrasound probe cable clamped may be needed; will evaluate during the mock up session.
   • Tammy will borrow the foot switch from Li Laboratory for the mock up session. Otherwise, the general setup is ready.
3. Decide immediate action items for next meeting.
   • See Immediate Action Items above.
4. Other.
   • None noted.
