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

本研究旨在评估根瘤菌的平均密度，机械稳定性和适用性。用环氧树脂粘合的刨花板，作为组织等效的幻像材料。刨花板用添加量为0％，5％，10％和15％的环氧树脂制成。CT扫描用于评估环氧分布。环氧含量为15％的样品符合日本工业标准。此外，通过显微镜分析和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值吻合良好，接近水值。微观分析和XRD结果均显示了环氧树脂在填充间隙和增加结晶度方面的效用。此外，用15％环氧树脂粘结的刨花板的标准偏差（SD）值与Catphan 600幻影的SD值非常匹配。此外，环氧树脂的15％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的机械和物理性能。刨花板将用作幻影材料。
