Purpose - Proof of Concept that visual recognition software can be applied to the field of limb alignment in real-time for surgical procedures - Improve the method of limb alignment used during surgical procedures - Create a new method that is more efficient, can be used in real-time, more economically profitable for hospitals.
Background and importance Current method is costly and time consuming Dependent on surgeon setup and calibration for accuracy
Methods Observe the actual surgical process of knee alignment Develop a step-by-step method and apply it to a visual recognition system Test and modify the program Continue development to add additional features such as auto alignment
Status Currently waiting to be scheduled to observe the knee alignment surgery Doing research on different software and computer vision systems
Choosing a Computer Vision System Criteria: Complexity Cost Expandability Efficiency Well-Documented Choices: Matlab LabVIEW Java C++ using OpenCV
Result OpenCV Useful functions concerning vision system Highly Versatile library Expandable using C++ Free
Future Work Hope to move into programming stage after this week Working at the very first step: recognition of different shapes Measure of success: Identifying objects with the camera
Conclusion The goal of this project is to accomplish a proof of concept that visual recognition software can be applied to the field of orthopedic limb alignment in real-time surgical procedure. We plan to accomplish this by using software and cameras to detect markers on a knee replacement tibial head. we hope to continue expanding the program to incorporate depth perception and to calculate alignment.
