Specimen 001-010

CMULTIS001-1

mock

• No Optorak collected, software under development

CMULTIS002-1

mock

• Extremity : Leg

• Optotrak output incorrectly indexed, not all data stored

CMULTIS002-2

mock

• Extremity : Leg

• Optotrak data correctly corrected

CMULTIS002-3

mock

• Extremity : Arm

• Humerus sensor file required debugging
• Firewall on Tyler's account prevented Optotrak connection, another was able to establish a connection

CMULTIS003-1

• Extremity : Arm

• Optotrak triax is thought to have come lose, skewing relative probe position for 4 positions in lower arm.

CMULTIS004-1

• Extremity : Leg

• Optotrak attachment plugs modified to receive #4-1 zinc plated screws instead of #3-3/4 brass screws to strengthen triax connection.
• Posterior lower leg ultrasound targeted fibula instead of tibia
• A new technique was developed to assist in determining lower tissue boundary in order to differentiate bone layers from tissue layers. By palpating the skin while viewing ultrasound, it is possible to see the compression of tissue or non-compression of bone.
• Data Analysis
  • F6 marker digitizing is poor, so only used F1-F5 for registration to the imaging data

  • Preliminary thickness comparison CMULTIS004-1_CTSlice_US_comparison.pdf
