Recurring Meeting of Cleveland Clinic Core Team

Date: September 13, 2016

Time: 10:30 AM EST

Means: In person meeting

Attendees:

1. Ahmet Erdemir
2. Snehal Chokhandre
3. Robb Colbrunn
4. Tara Bonner
5. Will Zaylor

Agenda:

1. Discuss immediate action items from the last meeting.
2. Discuss progress of tissue testing protocol evaluation.
3. Discuss segmentation plan and progress.
4. Decide immediate action items for the next meeting.
5. Other.

Ongoing Action Items:

• Ahmet
  • Complete reviewing the drafts of data manuscripts.
• Snehal
  • Work on reproducibility testing of confined compression.
  • Continue reproducibility testing of tension tests.
  • Implement zero stress-strain estimation to tissue testing analysis code.
  • Send Robb a copy of a Mach-1 protocol in its native format.
• All
  • Continue segmentation based on commitments listed in the Roadmap.

Notes:

1. Discuss immediate action items from the last meeting.
   • Most action items were related to the ongoing agenda items; refer to discussions below.
2. Discuss progress of tissue testing protocol evaluation.
   • Snehal conducted repeated tests on tissue samples with the procedure find contact – run preconditioning at high strain levels – find contact again – adjust target strain levels based on new contact point – run test. For confined compression, the results were satisfactory. The first and second test were almost identical (less than 5% error). For tensile testing, the results were encouraging. The responses from first and second tests were closer than before. Snehal will conduct additional tests, e.g. three repeated tests within the day. She will also test different tissues. Ahmet recommended that she update the protocols reflect this latest procedure.
   • Robb reminded Snehal for copies of Mach-1 protocols. If text based, these can be generated in a scripted fashion, e.g. using Python. This can facilitate Snehal's workflow by minimizing interactive data entries to set target strains and testing speeds.
3. Discuss segmentation plan and progress.
   • Robb has continued working on segmentation of patella bone and cartilage. He has been comparing his smoothed surfaces with those of Craig's. He noted that he had to iterate his segmentations for corrections.
   • Tara asked Ahmet questions about the boundary of meniscus. In soft tissue imaging, the boundaries of cortical bone and meniscus may be conflicting, particularly at the insertion sites of meniscal horns.
4. Decide immediate action items for the next meeting.
   • See Ongoing Action Items above.
5. Other.
   • Ahmet showed Will the cloud computing case study using femur-acl-tibia model. This may be relevant to Will's ongoing work.
