摘要： This invention puts forward a process of preparing butyl rubber. High gravity devices are used as polymerization reactor. The mixture of isomonoolefin and conjugated diolefin monomers and the diluent, and the mixture of the initiator and diluent are pumped at a certain ratio into a high-gravity reactor to conduct cationic polymerization in the high-gravity environment. After polymerization, the monomers and the diluent are removed from the product to obtain butyl rubber polymers with number-average molecular weight of 80000˜300000 and molecular weight distribution index of 1.9˜3.6. The high gravity polymerization method of this invention can tremendously intensify micro-mixing, mass transfer and heat transfer in the reaction. Compared to the conventional stirred polymerization method, this invention features small reactor volume, at least 30-fold shorter residence time of substances in the high gravity reactor, low cost, low energy consumption and high production efficiency.

摘要： A system and method for 3-D ultrasound image registration and 3-D motion estimation. A calibrated 3-D speckle function is first pre-determined for the transducer and the tissue to be scanned. A series of image frames are identified and grouped into 3-D big and small blocks. Blocks representing speckle are identified and then, a full width half maximum value sum-absolute-difference technique is used to obtain an out-of-plane motion estimation based on decorrelation characteristics throughout the volume. For in-plane motion estimation, cross-correlation characteristics between pairs of frames are compared and, using a minimum sum absolute value technique, an estimate of in-plane motion is obtained. Fuzzy logic techniques are then used to obtain more accurate estimates. Finally, the out-of-plane motion estimate is updated based on decorrelation characteristics of the speckle frames used for the in-plane determination using a full width half maximum value technique.

摘要： Three or four-dimensional ultrasound data acquisition for extended field of view imaging is provided. Multiple volumes are registered with respect to each other and spliced together to form an extended volume. The extended volume is a contiguous volume larger than a volumetric region that a multi-dimensional or wobbler transducer array is capable of imaging without movement. Information representing different volumes is registered with respect to each other by sensing the transducer position associated with each of the different volumes. The position is sensed using a position sensing mechanism, such as magnetic optical or gyroscope measurements. Acoustic data may be used to determine decorrelation of speckle or correlation of features to sense position. After the volumes are registered, any overlapping regions are compounded. The resulting extended field of view volume is displayed and manipulated for viewing by the user. A large volume or extended volume of the patient is used for assessing an organ, such as an entire fetus in OB applications.

摘要： A 3D image data set representing a volume of material such as human tissue is created using speckle decorrelation techniques to process successive 2D data slices from a moving, standard 1D or 1.5D ultrasound transducer. This permits the use of standard ultrasound machinery, without the use of additional slice-position hardware, to create 3D images without having to modify the machinery or its operation. Similar techniques can be used for special data processing within the imaging system as well to expedite the image acquisition process. Optionally, the image quality of 2D images can be enhanced through the use of multiple 3D data sets derived using the method.

摘要： Medical imaging uses cyclical motion analysis. Phase and/or amplitude analysis of variation for spatial locations in a sequence of images over one or more heart cycles is performed. For phase analysis, selected phase information is cyclically isolated as a function of the heart cycle. For example, a sequence of three images is associated with three different times during the heart cycle. In one image, phases over one range are highlighted. In subsequent images, phases over different ranges are highlighted. By showing the sequence of images in a loop with the shifting phase throughout the sequence, wall contractions are easily visualized. For amplitude analysis, information associated with a selected frequency band, such as the constant and fundamental frequency bands, are isolated. Images are then generated in response to the isolated information. The images have reduced speckle content due to the lack of higher order frequency information. Some higher order frequency information may be allowed to remain or added to avoid motion blurring. The isolated information also more likely has well defined borders or edges as compared to the information with the full bandwidth.
摘要翻译：医学成像使用周期运动分析。执行在一个或多个心脏周期上的图像序列中的空间位置的变化的相位和/或幅度分析。对于相位分析，选择的相位信息是循环隔离的，作为心脏周期的函数。例如，在心脏周期中，三个图像的序列与三个不同的时间相关联。在一个图像中，突出显示一个范围上的相位。在后续图像中，突出显示不同范围的相位。通过在整个序列中显示具有移动阶段的循环中的图像序列，壁收缩容易可视化。对于振幅分析，与所选频带（例如恒定频带和基频带）相关联的信息被隔离。然后响应于隔离信息生成图像。由于缺乏更高阶的频率信息，图像减少了斑点内容。可以允许一些更高阶的频率信息保留或添加以避免运动模糊。与具有全部带宽的信息相比，孤立的信息更有可能具有明确的边界或边缘。
