ABSTRACT

This study aims to evaluate the average density, mechanical stability, and the suitability of Rhizophora spp. particleboard bonded with epoxy resin as tissue-equivalent phantom materials. The particleboards were fabricated with added epoxy at levels of 0%, 5%, 10%, and 15%. CT scan was used to evaluate the epoxy distribution. The sample with 15% epoxy level complied with the Japanese Industrial Standards. Moreover, the crystallinity was measured by microscopic analysis and X-ray diffraction (XRD). The results showed that the values of mass density and effective atomic number of the studied samples were well agreed and close to the value of water. Both microscopic analysis and XRD results showed the utility of epoxy in filling up the gaps and increasing the crystallinity. In addition, the standard deviation (SD) value of fabricated particleboard bonded with 15% epoxy resin provided a good matching with the SD value of Catphan 600 phantom. Furthermore, 15% of epoxy, as a binder material, was considered the best percentage to achieve high performance and to enhance the mechanical stability of Rhizophora particleboards. In conclusion, epoxy resin improves the mechanical and physical properties of Rhizophora spp. particleboards to be performed as a phantom material.

摘要

本研究旨在评估 Rhizophora spp 的平均密度、机械稳定性和适用性。与环氧树脂粘合的刨花板作为组织等效体模材料。刨花板是用添加量为 0%、5%、10% 和 15% 的环氧树脂制成的。CT扫描用于评估环氧树脂的分布。环氧含量为 15% 的样品符合日本工业标准。此外，通过显微分析和X射线衍射(XRD)测量结晶度。结果表明，所研究样品的质量密度和有效原子序数数值吻合较好，接近于水的数值。显微分析和 XRD 结果都表明环氧树脂在填充间隙和增加结晶度方面的效用。此外，用 15% 环氧树脂粘合的制造刨花板的标准偏差 (SD) 值与 Catphan 600 模体的 SD 值提供了良好的匹配。此外，15% 的环氧树脂作为粘合剂材料，被认为是实现高性能和增强 Rhizophora 刨花板机械稳定性的最佳百分比。总之，环氧树脂改善了根霉属的机械和物理性能。刨花板作为幻像材料执行。
