For the first time, Rhizophora spp. (Rh. spp.) particleboard phantoms were developed using defatted soy flour (DSF) and soy protein isolate (SPI) modified by sodium hydroxide and itaconic acid polyamidoamine-epichlorohydrin (IA-PAE) adhesive. The microstructural characterization and X-ray diffraction patterns of the material revealed that the modified DSF and SPI adhesives became more compact and homogeneous when NaOH/IA-PAE was added, which prevented damage by moisture. It was confirmed that the composite is crystalline with (101), (002), and (004) orientations. Phantoms made of this material were scanned with X-ray computed tomography (CT) typically used for abdominal examinations with varying energies corresponding to 80, 120, and 135 kVp, to determine CT numbers, electron densities, and density distribution profiles. The radiation attenuation parameters were found to be not significantly different from those of water (XCOM) with p values [Formula: see text] 0.05 for DSF and SPI. The DSF- and SPI-based particleboard phantoms showed CT numbers close to those of water at the three X-ray CT energies. In addition, electron density and density distribution profiles of DSF-SPI-Rh. spp. particleboard phantoms with 15 wt% IA-PAE content were even closer to those of water and other commercial phantom materials at the three X-ray CT energies. It is concluded that DSF-SPI with NaOH/IA-PAE added can be used as a potential adhesive in Rh. spp. particleboard phantoms for radiation dosimetry.

测量用于CT幻影生产的改性脱脂大豆粉-大豆蛋白分离物型红树林刨花板的辐射衰减参数。

第一次，Rhizophora spp。（Rh。spp。）刨花板幻影是使用脱脂大豆粉（DSF）和经氢氧化钠和衣康酸聚酰氨基胺-表氯醇（IA-PAE）改性的大豆分离蛋白（SPI）开发的。该材料的微观结构表征和X射线衍射图表明，当添加NaOH / IA-PAE时，改性的DSF和SPI粘合剂变得更加致密和均匀，从而防止了水分的损害。证实了该复合物是具有（101），（002）和（004）取向的结晶。用通常用于腹部检查的X射线计算机断层扫描（CT）扫描由这种材料制成的模型，其能量分别对应于80、120和135 kVp，以确定CT数，电子密度和密度分布图。发现DSF和SPI的辐射衰减参数与水（XCOM）的p值没有显着差异。[公式：参见文本] 0.05。基于DSF和SPI的刨花板幻影在三个X射线CT能量下显示的CT数接近水。此外，DSF-SPI-Rh的电子密度和密度分布图。spp。在三种X射线CT能量下，IA-PAE含量为15 wt％的刨花板幻影甚至更接近于水和其他商用幻影材料。结论是，添加了NaOH / IA-PAE的DSF-SPI可用作Rh中潜在的粘合剂。spp。用于辐射剂量的刨花板幻影。基于DSF和SPI的刨花板幻影在三个X射线CT能量下显示的CT数接近水。此外，DSF-SPI-Rh的电子密度和密度分布图。spp。在三种X射线CT能量下，IA-PAE含量为15 wt％的刨花板幻影甚至更接近于水和其他商用幻影材料。结论是，添加了NaOH / IA-PAE的DSF-SPI可用作Rh中潜在的粘合剂。spp。用于辐射剂量的刨花板幻影。基于DSF和SPI的刨花板幻影在三个X射线CT能量下显示的CT数接近水。此外，DSF-SPI-Rh的电子密度和密度分布图。spp。在三种X射线CT能量下，IA-PAE含量为15 wt％的刨花板幻影甚至更接近于水和其他商用幻影材料。结论是，添加了NaOH / IA-PAE的DSF-SPI可用作Rh中潜在的粘合剂。spp。用于辐射剂量的刨花板幻影。结论是，添加了NaOH / IA-PAE的DSF-SPI可用作Rh中潜在的粘合剂。spp。刨花板幻影用于辐射剂量测定。结论是，添加了NaOH / IA-PAE的DSF-SPI可用作Rh中潜在的粘合剂。spp。用于辐射剂量的刨花板幻影。
