Summary
This study developed a tactile tumour detector (TTD) to analyze breast tissue and found good agreement between numerical and experimental results for detecting breast masses.
Area of Science:
- Biomedical Engineering
- Medical Physics
Background:
- Physician palpation is crucial for detecting abnormal breast masses.
- Modeling breast tissue with masses and analyzing tactile sensor function is essential.
Purpose of the Study:
- To simplify and model breast tissue with masses for tactile sensing analysis.
- To design and construct a tactile sensing instrument for detecting abnormalities.
Main Methods:
- Finite element method used to simulate mass effects on tissue surface.
- Development of a tactile tumour detector (TTD) with a robot-controlled probe.
- Experiments conducted within the linear elastic range of tissue to neglect dynamic effects.
Main Results:
- Maximum stress values used as a criterion for comparison.
- Investigated the relationship between stress criterion and mass parameters.
- Achieved good agreement between numerical simulations and experimental outcomes.
Conclusions:
- The tactile tumour detector (TTD) demonstrated potential for breast mass detection.
- Clinical trials compared TTD and clinical breast examination (CBE) sensitivity/specificity against sonography.
- Results showed good agreement between numerical and experimental findings.
