Ongoing Action Items:

• Tyler
  • Update wiki page on surgical tools protocol by adding details for each trial.
  • Revise/re-work manuscript on instrumented ultrasound.
• Ben
  • Integrate skin extrusion model into Abaqus.
  • Look into Sofa models with skin extrusion.
• Rici
  • Continue development of manuscript on in vivo indentation stiffness.
  • Continue development of manuscript on tissue thickness measurement comparisons.
• Ahmet
  • Determine strategies for model morphing.
  • Compile haptics libraries and SofaHAPI.
  • Review draft of model assembly manuscript.

Notes:

1. Manuscripts update.
   • Nothing to report.
2. Data dissemination update.
   • The Cleveland Clinic team did not receive any updates from Tod. Rici will reach out to him via e-mail.
3. In vitro testing status.
   • A wet mock was performed last week to confirm the whole testing procedure for characterization of surgical tools.
   • Tyler showed a video of the 3D strain measurement results for indentation. The results are good and the methods will be used as part of the final specifications.
   • Several bugs were found during the mock and we are working with Robb and Tara to fix the remaining bugs.
     • There is a delay in Optotrak data collection between the first and second data point.
     • It is desirable to specify the range of reported angles to be between -180 to 180 or 0 to 360 degrees
     • Triggering and synchronization signal to Vic3D signal was not being sent. This issue was later fixed.
   • Ahmet reviewed the order of the trials. Tyler will add details to describe what is performed in each trial.
   • Tyler asked Ahmet about the necessity of dissection trials, e.g. separating skin from fat and fat from muscle. Ahmet suggested to collect the data for interface mechanics, but noted difficulties and the possibility of protocol deviations as needed.

4. Modeling & simulation status.

   • Ben has been working to incorporate the extruded skin model into Abaqus. Element face numbering are different between Salome and Abaqus; he is working to convert them correctly to the Abaqus format.
   • Ahmet previously asked Ben to look at where we are at with Sofa. He has not had time to look into this yet.
   • Ahmet suggested having Sean, new engineering recruit, work on checking the new version of FEBio for in situ strain validity. Ben will advise him as necessary.
   • Morphing work is on hold until a decision is made on what assumptions to make.
5. Review of action items from past meeting.
   • All action items were related to the agenda items; refer to discussions above.
6. Decide action items for next meeting.
   • See Ongoing Action Items above.
7. Other.
   • None noted.
