Hypothesis
The filament mixing ratios will linearly affect the optical properties of the printed phantoms.
Conclusion
The study successfully demonstrates a method for creating complex optical phantoms with tunable properties using 3-D printing.
Supporting Evidence
- The method uses low-cost materials and is broadly accessible.
- The optical properties were systematically characterized across various filament mixing ratios.
- Three heterogeneous optical phantoms were designed and fabricated to demonstrate the technique.
Takeaway
This study shows how we can use 3-D printing to make special models that act like real tissues, helping scientists test their tools.
Methodology
The study involved 3-D printing phantoms using multi-color mixing extruders and characterizing their optical properties.
Limitations
The average error in optical property predictions was between 12%-15%.
