Immediate Action Items:

• Ahmet
  • Disseminate oks008 MR image sets.
  • Detail image segmentation specifications.
  • Review specifications on registration to evaluate Connor's contributions.
  • Review specification on patellofemoral contact pressure analysis.
  • Review specification on tibiofemoral joint kinematics/kinetics analysis.
  • Review specification on optical thickness measurements.
  • Provide a sample patellofemoral joint kinematics/kinetics file.
• Craig
  • Meet with summer students to go over convergence optimization wiki and describe workflow.
  • Provide sample MR images for oks008 in the relevant wiki page.
• Snehal
  • Complete notes section of June 9, 2015 meeting.
  • Test all tissue types at 20%/s to evaluate the capacity for a simplified testing scheme (for next two weeks).
  • Buy a camera for optical measurement system.
• Robb
  • Conduct post-experiment calibration of pressure sensor used for oks008 testing.
• Connor
  • Start segmenting registration markers
  • Develop script to accommodate transformation between probed patella registration marker points and sphere centers.
• Diana
  • Start verification of contact pressure analysis with Robb and Tara (using Tekscan original files).
  • Work with Omar to read and analyze patellofemoral kinematics/kinetics data (including line of action of quadriceps load).
• Omar
  • Work with Diana to help her read and analyze patellofemoral kinematics/kinetics data.
  • Implement normalization of RMS errors in reproducilibity analysis.
• Raghav
  • Start implementing camera interface to optical measurement script.
  • Start thinking about uncertainty quantification of optical measurement system.

Ongoing Action Items:

• Ahmet
  • Dissemination of joint mechanics testing data.
  • Prepare flowcharts to describe data flow for pre-processing of joint kinematics/kinetics data.
• Craig
  • Anatomical imaging manuscript.
  • Large-scale analysis of simulation parameters for convergence.
• Snehal
  • Continue interacting up with Biomomentum, Inc. about mechanical testing system tuning features.
  • Complete the additional structured testing plan for tuning the system for different sample sizes, strain levels and strain rates.
  • Pivot shift manuscript.

  • Cruciate ligament modeling & simulation.

  • Evaluate alternative tissue testing strategy.
• Robb
  • Patellofemoral joint experimentation manuscript.
• Tara
  • Tibiofemoral joint experimentation manuscript.

Notes:

1. Discuss immediate action items from the last meeting.
   • Ahmet had some issues with SimpleITK to convert MR images from DICOM format to NIFTI format. He will follow up in the upcoming week to resolve this issue. Diana created a wiki page to draft specifications for patellofemoral joint contact analysis.
   • Craig was at SB3C last week to present the imaging work for Open Knee(s). He will follow up with his action items in following weeks.
   • Snehal has been working on Mach-1 system to resolve issues and she has been communicating with the Biomomentum, Inc. group. Currently, there has not been a resolution to effectively tune the system to accommodate testing at 100%/s strain rate. She will test all the tissues at 20%/s strain rate to ensure the fall back testing procedure works appropriately. Snehal has been providing sample data for summer students' projects on a need basis.
   • Robb has been on vacation and also at the SB3C; he will work on post-experiment calibration of oks008 pressure sensor after he comes back.
   • Tara provided laxity data for oks008. The group can discuss this when Robb and Tara comes back from vacation and business related trips.
2. Discuss mid-term presentations to be given by research students.
