目的在双能CT（DECT）产生的光谱数据集中有大量的定量信息。在本研究中,将多能量数据集上进行的纹理分析性能与65 ke V虚拟单色图像（VMI）的性能进行比较,并以2种最常见的良性腮腺肿瘤分类为测试范例。方法对42例病理证实的Warthin瘤（25例）或多形性腺瘤（17例）进行评估。纹理分析是在40;40 keV VMI范围内以5 ke V递增（多能量分析）或仅以65 keV VMI进行的,通常认为其等效为单能CT。采用单独的随机选择的训练和测试集或整个病人组来构建随机森林（rF）模型用于结果预测。结果使用多能纹理分析独立测试集中的肿瘤分类准确度、敏感度、特异度、阳性预测值、阴性预测值分别为92%、86%、100%、100%、83%,而单能分析以上各值分别为75%、57%、100%、100%和63%。结论与65 keV VMI的单能质地分析相比,多能量纹理分析在良性腮腺肿瘤具有更好的分类性能。

In this study, the microstructure and second-phase particles in yttrium （0.05 wt.%and 0.8 wt.%） bearing Fe-10Ni-7Mn steels were characterized. The results of X-ray analysis as well as scanning electron microscopy coupled with energy dispersive X-ray spectroscopy indicated the formation of （Fe, Ni, Mn）17Y2 precipitates with hexagonal structure in a Fe-10Ni-7Mn-0.8Y （wt.%） alloy. Lattice parameters of these precipitates were calculated as follows：a=0.8485 nm and c=0.8274 nm. Formation of Y2O3 sub-micron particles was also confirmed in both yttrium bearing steels via electrolytic phase extraction method. The effect of these precipitates on the prior austenite grain size was investigated. The results revealed that these precipitates had an effective role in controlling the prior austenite grain size.

In this study, highly porous forsterite scaffolds with interconnected porosities were synthesized using multi-step sintering(MSS) method. The starting powder was nanosized forsterite, which was synthesized from talc and magnesium carbonate powders. The phase composition, average particle size and morphology of the produced forsterite powder were characterized by X-ray diffraction technique(XrD) and transition electron microscopy(TEM). Forsterite scaffolds were produced by foamy method using polymeric sponges. MSS process including three steps was used to efficiently sinter the forsterite nanopowders without destroying the initial porous structure of polymeric sponges. The results showed that MSS technique is an efficient and appropriate procedure to produce highly porous forsterite scaffolds with pore size in the range of 100-300 μm. The compressive strength, compressive modulus and porosity of C12 specimen(sintered at 1650℃ for 1 h with subsequent annealing at 1000℃ for 1000 min) was 1.88 MPa, 29.2 MPa, and 72.4%, respectively, which is very close to that of cancellous bone. The approach studied in this research can be developed for other nanostructure ceramics to produce highly porous scaffolds with interconnected porosities for load bearing applications.
