Abstract Phantom has been widely used in the medical field, especially for radiography. The aims of this study is to determine the linear attenuation coefficient and mass attenuation coefficient of the composite gelatin, particleboard from Rhizophora spp, and Polyvinyl Alcohol (PVA) as constituents of soft tissue phantom. Phantom has been synthesized from gelatin for various concentrations (16%, 20%, 24%, and 28%) with additional particlesboard from Rhizophora spp rods and Polyvinyl Alcohol (PVA) as adhesive. Gelatin is dissolved using distilled water for 30 min then insert the Rhizophora spp particleboard Polyvinyl Alcohol (PVA) as a binder. The characterization is carried out for determining the swelling ratio, the CT-Number, the Region of Interest (ROI), and the characteristics bonding between the atoms by Fourier transform infra-red (FTIR). The C = C bonding play an important role as a cross linking bonds between the atoms from gelatin and the atoms from the particleboard. The samples were irradiated by using X-rays for the energy 120 kV with 50 mA. The linear attenuation coefficient is 0.238 cm–1 with a Half Value Layer (HVL) value is 2.911 cm. Phantom with a composite Gelatin-PVA-Rhizophora spp particleboard has the potential for liver phantom applications.

用于软组织模型应用的复合明胶/Rhizophora SPP 刨花板/PVA

摘要 Phantom 已广泛应用于医学领域，尤其是在放射学领域。本研究的目的是确定作为软组织模型成分的复合明胶、刨花板和聚乙烯醇 (PVA) 的线性衰减系数和质量衰减​​系数。Phantom 是由各种浓度（16%、20%、24% 和 28%）的明胶与来自红树属植物棒的额外刨花板和聚乙烯醇 (PVA) 作为粘合剂合成的。使用蒸馏水溶解明胶 30 分钟，然后插入红树属刨花板聚乙烯醇 (PVA) 作为粘合剂。进行表征以确定溶胀率、CT 数、感兴趣区域 (ROI) 以及通过傅里叶变换红外 (FTIR) 进行的原子间键合特征。C = C 键作为明胶原子和刨花板原子之间的交联键起着重要作用。通过使用能量为 120 kV 和 50 mA 的 X 射线照射样品。线性衰减系数为 0.238 cm–1，半值层 (HVL) 值为 2.911 cm。带有复合明胶-PVA-Rhizophora spp 刨花板的模型具有肝脏模型应用的潜力。
