1.Result: In the reconstruction of a simulated Phantom data, OSEM gives better images with higher spacial resolution and lower noise, as compared with traditional FBP method especially under noisy acquisition situation in fan-beam scanning, and in a certain extension the image quality is proportional to the product of the iterative number and the subset order, while computing time is only related to the iterative number.
通过对模拟的Phantom扇束投影数据的重建,结果: OSEM重建效果好于传统滤波反投影(FBP)重建的结果,尤其是在有噪声情况下,在一定范围内重建质量与迭代次数和子集划分个数成正比,而计算时间仅仅与迭代次数正比。
2.Materials and Methods: 12 soap models simulating the pulmonary nodules of different size and shape loaded on the Philips Pulmonary Phantom and 30 patients with pulmonary nodular lesions of different pathology were subjected to digital radiography (Siemens Polystar. Fluorospot H) and processed with 0% to 100% edge enhancement.
材料和方法：使用SiemensPolystar·FluorospotHX线数字成像和处理系统分别对12个用Philips肺部Phantom叠加肥皂制作之不同大小及形态之结节模型以及30例不同病理之肺部结节性病灶，进行摄片及图像后处理，分别作0％～100％边缘增强。
3.The detailed structure of Cartesian Coordinate RAMS Master Manipulator is stated and the concise structure of PHANToM Desktop is introduced.
对笛卡儿坐标式RAMS主操作手的具体结构进行了详细的阐述,并对关节式RAMS主操作手PHANToM进行了简单的结构介绍。
4.The Torso phantom represents the trunk of an adult man that is 170 cm high and weight of 65 kg. After these images were segmented,cropped,and resized,a 3-dimension voxel phantom was created. The voxel phantom includes more than 2 million voxels,which size was 2.73 mm×2.73 mm×3 mm.
代表身高170 cm、体重65 kg的成年男子躯干(Torso)物理模型经CT扫描获取了其断层信息图像,对这些图像进行组织器官分割、剪切、缩放等处理后,建立了含有200多万个大小为2.73 mm×2.73mm×3 mm的体素的三维体素模型。
5.I placed three phantom bets and made a phantom loss of £145.
我下了三次模拟赌注，结果模拟损失了145英镑。
6.For that reason, watching The Phantom Menace for the first time was a little disorienting, Natalie said. "I was very surprised when I saw The Phantom Menace, because it was completely different visually from anything I had seen," she recalled. "We shot a lot against blue screens, and a lot of the characters were computer generated.
出于这个原因，第一次看到《幽灵的威胁》时她有一点迷惑，娜塔莉说：“我看《幽灵的威胁》时非常的惊讶，因为和我曾经看到的一切都完全不同了，”她回忆说，“我们在蓝幕前拍了许多镜头，许多角色都是计算机生成的。
7.Dr Flor and her colleagues studied people who suffer from a form of phantom limb known as a telescoping phantom.
福罗博士和她的同事研究了一种叫“伸缩性幻觉”的幻肢。
8.A superimposed circuit derived from two suitably arranged pairs of wires called side circuits, with each pair of wires being a circuit itself and at the same time acting as one conductor of the phantom circuit.
一种由称作半边电路的两对线路经适当安排形成的叠加电路。每一对线本身既作为电路，同时又充当幻象电路的一个导体。
9.The almost violent serenity of the funereal moment had disappeared; the phantom of social justice tormented him. He, who generally returned from all his deeds with a radiant satisfaction, seemed to be reproaching himself.
送死时那种强迫的镇静已经消逝了，社会威权下的鬼魂和他纠缠不清，他平时工作回来，素来心安理得，神采奕奕，这时他却老象是在责备自己。
