使用先前开发的方法制造了由嵌入在光学透明的有机硅基质中的二氧化硅微球组成的光学散射体模。然而，经常遇到多种问题，如球体聚集、吸附到铸件上和硅酮收缩。这些问题的解决方案，并提出了一种改进的方法，将这些解决方案。改进后的方法提供了良好的可靠性和再现性，用于创建具有均匀散射系数的体模。我们还提出了减少球体聚集的证据。
Optically scattering phantoms composed of silica microspheres embedded in an optically clear silicone matrix were manufactured using a previously developed method. Multiple problems, such as sphere aggregation, adsorption to the cast, and silicone shrinkage, were, however, frequently encountered. Solutions to these problems were developed and an improved method, incorporating these solutions, is presented. The improved method offers excellent reliability and reproducibility for creating phantoms with uniform scattering coefficient. We also present evidence of decreased sphere aggregation.
