Summary
The optimal spring strength for a biological tissue hardness meter (PEK) to image breast cancer is 4.90 N. This setting provides the largest measurement range and clearest imaging of indurations in palpation models.
Area of Science:
- Biomedical Engineering
- Medical Device Development
- Diagnostic Imaging Technology
Background:
- Developing a multipoint hardness measurement system for biological surfaces.
- Investigating the spring strength of a biological tissue hardness meter (PEK).
Purpose of the Study:
- Determine the optimal spring strength for a biological tissue hardness meter.
- Enhance the understanding of hardness distribution on biological body surfaces.
- Improve imaging of subsurface abnormalities like breast cancer.
Main Methods:
- Tested six types of gel sheets with varying spring strengths (1.96 N to 9.81 N).
- Measured hardness distribution on induration-embedded and breast cancer palpation models.
- Utilized a Contour Fill Chart to visualize hardness data.
Main Results:
- 4.90 N spring strength yielded the largest measurement range (≤3.0 N load, mean hardness 5.14 mm).
- Induration imaging was successful across all tested spring strengths in the embedded model.
- 4.90 N provided the most effective imaging for the breast cancer palpation model.
Conclusions:
- 4.90 N spring strength is optimal for the PEK hardness meter.
- This setting is best suited for imaging cancerous tissue in breast cancer palpation models.
- The findings contribute to developing advanced diagnostic tools for biological tissue analysis.
