Summary
A new microcomputer system uses potentiometers to capture spatial data for orthopaedic measurements. This system converts raw data into precise 3D lengths and angles for clinical applications.
Area of Science:
- Biomedical Engineering
- Orthopaedics
- Medical Instrumentation
Background:
- Accurate spatial measurement is crucial for orthopaedic diagnosis and treatment planning.
- Existing methods for spatial data acquisition in orthopaedics can be complex or limited in scope.
Purpose of the Study:
- To design and describe a novel microcomputer-based system for acquiring spatial information.
- To enable precise three-dimensional (3D) orthopaedic measurements using readily available transducers.
Main Methods:
- Development of a hardware system incorporating three potentiometers as transducers.
- Implementation of software algorithms for data acquisition and processing.
- Calibration and validation of the system for spatial data conversion.
Main Results:
