随着社会不断发展,肿瘤发病率呈逐年升高态势,提升早期病灶检出率有助于临床医生制订有效诊疗方案,对提高肿瘤患者生存率及生活质量意义重大。全身磁共振成像(whole body-magnetic resonance imaging,WB-MRI)对早期肿瘤病灶检出及肿瘤高危人群筛查具有巨大优势。WB-MRI具有无电离辐射、软组织分辨率高的特点,能够弥补正电子发射计算机断层扫描(positron emission tomography/computed tomography,PET/CT)辐射剂量大、软组织分辨率低的缺点,并在实际应用中得到验证。WB-MRI可应用于肿瘤早期病灶检出、影像诊断、临床分期、治疗效果评估等方面,同时可敏感检测出转移性骨肿瘤的骨质破坏情况及血液性肿瘤的骨髓浸润。综上,本文针对WB-MRI在呼吸系统肿瘤、消化系统肿瘤、血液系统肿瘤、骨转移肿瘤检出以及肿瘤高危人群筛查方面的临床应用进展作一综述。

采用CFD-DEM的方法对气固循环流化床提升管内的气固流动特性进行模拟,建立了基于图像处理的分析颗粒聚团的方法,重点研究了颗粒聚团在床层内的整体分布以及颗粒聚团的特性,包括颗粒聚团的倾角、球形度以及长短轴比的概率密度分布以及它们在床层内的轴向和径向上的分布特性。研究结果表明,聚团在床层内的分布较宽,较小的聚团居多,边壁区域附近易形成较大的聚团。聚团的数目沿床层高度方向先增加后减少。聚团倾向于以偏离球形聚团、较大的倾角形式存在,其长短轴比值在2-4之间。

为解决图像放大过程中有效地保证边缘锐化的图像插值难题,提出多层次轮廓约束的图像放大算法.首先利用检测算子对图像进行预处理,将图像分为边缘区域、平坦区域;其次,针对图像边缘区域进行自适应梯度扩散获取适当的边缘轮廓层作为图像放大约束;最后对轮廓层直接进行曲线插值重采样,不额外增加边缘层数,以保证放大后的图像在视觉上的边缘清晰.对于非轮廓层的平坦区域,构建双三次Coons插值曲面并进行重采样,保持了平坦区域的平滑性.测试图像为自然图像和医学图像,自然图像的来源是set5和set14测试集,实验对比方法主要从客观效果、视觉效果、时间复杂度3个方面进行比较.实验结果表明,采用该算法得到的放大图像不仅可以保持轮廓清晰,且PSNR及SSIM指标超过了大多数经典的插值算法以及目前流行的基于机器学习的算法.

为满足高速铁路地震预警系统列车实时定位的需求,提出1种列车无线指纹定位方法。首先,使用高速列车采集铁路沿线无线通信系统接收电平、定时提前量及公里标等信息,基于无线传播模型将定时提前量映射为无线电波传播损耗,进而生成无线指纹并建立其数据库;然后,根据列车运行轨迹特征动态划分信号空间,限定无线指纹搜索范围,建立统一量纲的无线指纹相似度计算模型;最后,使用加权k-近邻算法在无线指纹数据库中搜索与待定位列车相匹配的无线指纹,计算列车的位置。在高速综合检测列车安装测试设备,分析检验列车无线指纹定位得出的位置与实际位置的差值,结果表明列车平均定位误差为82m,可满足高速铁路地震预警系统的需求。
