'''Notes:''' 1. Discuss immediate action items from past meetings. * Ahmet received the quote from the Medical Device Solutions group at Cleveland Clinic for the design and manufacturing of the ultrasound probe - force transducer interface and the handle. He has been interacting with the designers to implement necessary features. * Ahmet incorporated recommendations from mock-up testing to the in vivo testing specifications page and discussed them with the group. * Ahmet reviewed specifications page for indentation modeling and provided comments for Ben to address. * Ahmet also went over the instrumented ultrasound infrastructure page and provided notes for Robb to expand documentation. * Tammy came up with branding of the integrated ultrasound - force transducer system and created a logo: LInUS, Load-transducer Instrumented Ultrasound System. * Tammy will order ultrasound gel from Cleveland Clinic store room. She noted that she will not necessarily need a hand rest and she can improvise foot rest. She will use the Cleveland Clinic laundry services for towels and sheets. * Tammy still needs to write up detailed in vivo testing protocols in the relevant specifications page. She will further explore standardization of surface mat by talking to Georganne Botek of Cleveland Clinic. She also needs to order snowboard/ski bag for in vitro testing. * Tammy talked to Russ Fedewa about the storage capacity of the ultrasound system. She was informed that the team do not have to remove imaging files every day. Tammy will transfer the data to an in-house data management system immediately after data collection. The files will be removed from the ultrasound system every two weeks. This needs to be documented as part of the in vivo testing protocols. Related to data transfer, Tammy mentioned that the ultrasound imaging on the same subject may need to be split into two subject to allow fitting the data in CDs. * Tammy talked to Snehal Chokhandre and confirmed that a cadaver leg specimen is available for fine-tuning of magnetic resonance imaging protocols and in vitro mechanical testing procedures. * Ben was trying to learn SOFA for surgical simulation. Yet, without the Modeler, he has been having difficulties. There were problems in compilation of Modeler in his Linux system. Ahmet will take a look at it. * Ben noted that the tetrahedral element performance was not that great as appropriate solutions require largely increasing the mesh density. Ahmet recommended him to work on an even simpler model: a simple prism model under indentation - 10 mm thick; 30 mm width/length; 250 mm radius spherical indenter; 5 mm indenter displacement. He will develop models with hex and tet meshes at different densities; solve the problem and report reaction force and the peak effective stress at full indenter displacement. This will not only allow convergence of mesh when using the same type of elements but will also confirm the equivalence of hex and tet mesh performance. Simulation cost, e.g. Simulation cost; e.g. memory and computing time should also be reported. * Ben and Ahmet went over geometric modeling and meshing using Salome. Ben has been trying to import meshes generated by Salome to !Preview / FEBio. Ahmet recommended him to talk to Craig Bennetts, who has wrote some Python scripts to convert UNV files (a mesh file that Salome can export) to INP files (a mesh file that !PreView can import). * Ben scanned the ultrasound probe 14L5 again to get cleaner surface geometries. He will provide the new scans. * Robb needs to document data file labeling for in vivo testing and provide a detailed inventory in the infrastructure page of the instrumented ultrasound system. * Tara was not in the meeting. Tammy has been communicating with her for implementation of additional anthropometric measurements to the in vivo data collection interface. 1. Readiness for in vivo testing. * Work on data collection system is ongoing: * Tara will incorporate minor updates to data collection scheme. * Robb will start working on the integration of orientation sensor. * Ahmet will continue working with the Medical Device Solutions at the Cleveland Clinic to oversee the design and manufacturing of fixtures to hold different ultrasound probes. * Tammy will start detailed documentation of in vivo testing protocols in the wiki. * Also, refer to relevant discussions listed in the agenda item above. 1. Decide immediate action items for next meeting. * See Immediate Action Items above. 1. Other. * A candidate for the research engineer position will be visiting Cleveland Clinic on upcoming Friday. Ahmet asked all team members to meet him.
