Notes:

1. Discuss immediate action items from past meetings.
   • All action items were related to the recurring agenda items; refer to discussions below.
2. In vivo testing progress.
   • Tammy has recruited several subjects and she will resume testing next week.
   • Tara updated the data collection to report the magnitude of compressive forces. This will help Tammy to appropriately evaluate the loading during ultrasound imaging.
   • Tyler wrote a quality assurance Python script which displays the load cell data and associated sample ultrasound images. Tyler showed the group the plots for MULTIS001 and explained the process. The calculation of delta T from the file association script was proved reliable by using the the temporal shift to synchronize the data then extract DICOM images at each pulse peak. Each image showed the pulse at the exact peak indicating the temporal shift delta T is accurate plus or minus one frame (the sampling frequency of the ultrasound). After developing the script, Tyler handed it over to Rici to use for the data analysis.
   • The group went over data from MULTIS001 using figures generated by Tyler. All data seem to be in order, except high compressive forces in a few anatomical imaging trials.
3. Readiness for in vitro testing.
   • Tyler is awaiting reallocation of funding categories to order Optotrak parts and computer monitors. The quotes for both Optotrak and computer monitors have have been prepared.
   • The specimen order, which was previously stuck in purchasing system, has been placed.
   • Ahmet and Robb discussed the needs to incorporate Optotrak systems in to the existing data collection system for the first phase of in vitro testing.
   • Tyler and Robb discussed their ideas for instrumenting the surgical tools for the second phase of in vitro testing.
4. Data analysis update.
   • Rici completed the first iteration of the manual thickness measurement script. The user can drag vertically constrained points on an interactive plot and export thickness data to an XML. Ahmet mentioned to also save corresponding force data with each set of thickness measurements from a specific image. He also noted that it may be good to allow the user to analyze and save data from multiple images. Ahmet asked Rici to document her work in the wiki.

5. Modeling & simulation specifications.

   • Ben is working on morphing geometric models in Blender. He found the software powerful yet he has had difficulties in setting parameters in Blender to specifically define morphing parameters. His goal is to use the readily available STL surfaces segmented from MRI with subject-specific tissue thickness and anthropometric measurements of in vivo experimentation in order to create a new model.
   • Ben asked Ahmet about his action item to reach out to SOFA forums for compilation of HAPI. Ahmet has not done that. Yet, he noticed a relevant post in the forums to compile SOFA to use Novint Falcon, the haptic device that will be used for prototyping. Ben was also aware of this post and looking for follow up replies.
6. Decide immediate action items for next meeting.
   • See Immediate Action Items above.
7. Other.
   • None noted.
