• Ahmet, Craig and Snehal
  • Check with Chris Flask to setup and complete an full mock-up imaging session.
  • Prepare mock-up specimen for imaging.
• Robb and Tara
  • Complete robotics testing related upgrade tasks.
• Snehal
  • Respond requests in the infrastructure page of tissue testing experimentation.
  • Respond requests in tissue sample preparation pages.
• Cara
  • Meet everyone to understand their data management needs.

Notes:

1. Discuss immediate action items from the last meeting.
   • Ahmet added Cara and Dylan to the project team.
   • Jason summarized the specimen transportation page
   • Craig sent a detailed email to the imaging at UH about our current issues. Ahmet also discussed with Chris Flask about our needs. We'll need another trial session. Ahmet summarized the approach on the imaging specifications page.
   • Robb ordered base plugs for the tibia and femur. The patella marker set was redesigned by Craig and is currently being drawn by a member of Medical Device Solutions. It is now a “wrapping” design that somewhat conforms to the patella and will also wrap inside the transportation tube. The immediate action for the patella marker is to modify and manufacture the design per our discussion. Essentially, this includes adding some chamfers and probing divots to the existing design.
   • Tara had the Tekscan order placed by the BME administration.
   • Tara also updated the specimen preparation page. This will be discussed in the specific action item.
   • Craig and Tara verified that the existing patella marker is too large.
   • We still assume the order with Biomomentum is on schedule.
2. Update on imaging.
   • Ahmet summarized his discussions with Chris Flask under the “OAI style” imaging table. Ahmet confirmed that the OAI settings were a starting point. Chris provided his interpretation of the image settings. There was a miscommunication about image alignment. As long as the specimen does not move, all image sets should be aligned in the same coordinate system. We do not require “co-localization”, which we interpret as voxel alignment between image sets.
   • The progression of sequences, from 1 to 3, were summarized. Sequence 3, the MESE settings, still need to be tested. Ahmet proposes that the next imaging test session is essentially a mock-up of the work flow. Ahmet and Craig will schedule the next test session.
   • We discussed alternative registration markers for the tibia and patella. As of now, we'll default to the traditional approach but are considering alternative designs that utilize the existing plugs (for the Optotrak)
3. Update on pressure measurement.
   • Robb and Jason will attempt an equilibration and calibration approach for pressure measurements.
4. Update on manufacturing of testing accessories.
   • Ahmet believes that most, if not all, accessories are manufactured. This primarily refers to the hardware. Now the software needs to be updated to reflect the hardware changes. Dylan received the new probe and calibration is ongoing. Robb summarized an issue with a new computer and corresponding control of the robot. The older computer can always be used as a default but a new setup is being troubleshot.
5. Update on specimen preparation specifications.
   • Tara added a pdf of the specimen labeling approach for soft-tissue testing. Numbering was proposed, which should be tied to metadata that describes the test.
   • Discussion centered around metadata and its association with the specimen numbering/naming. The approach will be decided as we progress and a convention for populating metadata and the naming should be.
6. Discuss progress of all other tasks.
   • Snehal will update the Experimentation infrastructure page to summarize the tissue testing facilities, grips, etc.
   • The saline bath and associated heater were discussed. Images of the specimen during testing, due to the cylindrical bath, will be distorted in the current setup. The tank will likely need to be modified to provide a clear/undistorted picture of the specimens during testing.
7. Decide immediate action items for the next meeting.
   • Ahmet summarized the Immediate Action Items (see above). The team agreed that the tasks were appropriate.
8. Other.
   • None noted.
