Silica dioxide (also known as silica, silicon dioxide, SiO₂, silica powder) is an acoustic scattering additive used in medical simulation to create ultrasound-visible phantoms. When dispersed in agar or gelatin gels, silica particles produce the speckle pattern characteristic of real tissue under ultrasound imaging.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Soft tissue (ultrasound phantoms) | Yes | Partial | Additive for ultrasound echogenicity. Recipe: 1–5% silica by weight in agar or gelatin base. Produces speckle pattern characteristic of real tissue under ultrasound. Higher concentration (5%) produces hyperechoic targets; lower concentration (1–2%) for soft tissue background. |
