Immediate Action Items:

Notes:

  1. Discuss immediate action items from the last meeting.
    • The group discussed tekscan components, Jason will follow up with Tekscan regarding pricing. Tara mentioned using the foot pressure device for equilibration. We should check the range for this device.
    • Chris Flask (UH imaging) emailed Jason back about coordinate frame alignment for MRI. He stated that we "cannot rely on the images to be aligned" but that there was a way to force them to be. Jason will follow up during the test session.
    • Ahmet wrote the meeting minutes from last week and also provided feedback for the specimen preparation page.
    • Tara provided an updated on a potential new specimen. It fits the qualifications for an old female specimen and it does not appear to the arthritic (minus a few osteophytes that were identified by Dr. Jones). We assume it is healthy but realize that once it is opened it may turn out to be arthritic. This specimen will be ordered. Tara will follow up soon about ordering the young specimens.
    • Robb discussed the list of accessories for new tissue testing machine. Ahmet advised Robb to rely on the testing procedures outlined in a manuscript from the j2c project to qualify the testing needs for development of the hardware. It was decided to include this list of hardware in the infrastructure page along with an "accessories" list.

    • Ahmet said Izzy is following up with the tissue testing machine. Currently, the order is not in the hands of BioMomentum.

    • Tara summarized "cleaned" versus "intact" joint kinetics/kinematics. Data was utilized from a previous CoBi Core research sponsor. This question drives the choice to test with or without tissue during OpenKnee testing. Refer to summary page (to be populated) though it appears there is an affect of the skin/capsule, especially for IE rotation. Specimen 2 from the previous testing appeared to match loads between "cleaned" and "intact" states. Ahmet proposes that we test with skin, knowing that there is some uncertainty that may be attributed to the surrounding tissues, especially for IE rotation. We should consider another controlled study with successive cleaning of cadaver knees and multiple loading cycles at each state.

    • Robb discussed hardware specifications and he upated the details related to the robot that will be used to test the OpenKnee joints.

    • Craig will update the imaging specifications page for next week. The specifications page will include the current protocol on top with the "notes" moved below or to a discussion page. Craig will also make sure the velcro installation for the transportation device is ready to go before the imaging test session.
    • Ahmet will prepare the joint experimentation wiki page for community review. This will be accomplished by adding a title to the header, much like the specimens specifications page.
    • The group should review the specimen preparation page. Tara said the details will change since we decided to test with the skin intact. She will update.
  2. Discuss progress of all other tasks.
    • Previous meeting minutes were browsed to make sure we took care of the necessary items. Ahmet summarized the naming conventions in the meeting notes. Users/developers can start with this perspective to develop these specifications.
    • All listed tasks were discussed. Robotics testing specifications will be closed. There is an upcoming conference call with Stanford. They (Stanford) should provide an update from the previous meeting, where they had a number of tasks to accomplish.
    • Next week the group should provide a test problem for outlining creation of "element sets" in FE analysis for the Utah group. Ahmet and Jason will meet early next week to discuss.
    • The group decided that the imaging infrastructure details should be moved from their current location.
    • Robb/Tara updated the tasks related to robotics capabilites and specifically the Registration between the Optotrak cameras. Registration between Optotrak cameras is under investigation. The initial test with additional (8 total) IRED markers to define the tip of a probe did not appear to help with this issue (as opposed to the previous closely placed 3 IRED probe). Discussion centered around development of an approach to quantify the potential errors associated with Optotrak measurements from both cameras, either individually or together.
  3. Decide immediate action items for the next meeting.
    • Action items were discussed, meeting attendees agreed to their specific tasks. See above for details
  4. Other.
    • Ahmet summarized the wiki behavior with respect to image linking or attaching. We should be aware that using "attachment" the image can be lost (the file needs to be uploaded to the repository). Users can consider using the "link" option to the repository. That way the image itself in under version control.

    • An aside from Robb, let's consider creating specimen preparation videos to capture the "nuances" of this process. As Robb said, we can formally write this down but this may be well supported by videos. Ahmet "is a fan" and we should used OpenKnee as an excuse to create these videos. An OpenKnee YouTube channel may be created and linked with the existing BioRobotics YouTube channel. Robb will provide leadership on the BioRobotics side, Ahmet from the OpenKnee and eventually Jason from the Cobi Core side. The goal is to generate promotional and training videos for all groups/projects. Ahmet will setup a monthly meeting.
