AbstractThe award will be used to purchase a laboratory scale x-ray computed tomography system capable of sub-micron spatial resolution. The system is capable of imaging the internal structure of a wide range of materials. This capability will initially be exploited to answer questions regarding the uptake of trace metals in the environment, bone mineral density, defects in micromachines, membrane and filter processes, artery roughness and fluid flow, and microstructure-property relationships for a variety of heterogeneous and functionally graded materials. All these fields will be aided by the parallel adaptation and implementation of sophisticated 3D image analysis routines to maximize the useful quantitative information that can be extracted from the data. The tomography system is the first unit of its kind capable of sub-micron spatial resolution, representing nearly an order of magnitude improvement over other commercially available laboratory systems. This resolution improvement allows us to capture microscopic 3D spatial information at critical length scales, enabling us to make new measurements and challenge old assumptions in a wide range of scientific fields. The instrument will be the centerpiece for a 3D imaging facility that will be a resource for research and outreach in New England and beyond.

该奖项将用于购买能够实现亚微米空间分辨率的实验室规模的X射线计算机断层扫描系统。该系统能够对多种材料的内部结构进行成像。这种能力最初将被用来回答有关环境中痕量金属的吸收、骨密度、微机械缺陷、膜和过滤过程、动脉粗糙度和流体流动以及各种异质和功能梯度材料的微结构-性能关系的问题。所有这些领域都将得到并行调整和实施复杂的三维图像分析例程的帮助，以最大限度地从数据中提取有用的定量信息。层析成像系统是第一个能够实现亚微米空间分辨率的同类设备，比其他商用实验室系统提高了近一个数量级。这种分辨率的提高使我们能够在关键长度尺度上捕获微观3D空间信息，使我们能够在广泛的科学领域进行新的测量和挑战旧的假设。该仪器将成为3D成像设备的中心部件，该设备将成为新英格兰及其他地区研究和推广的资源。
