MICRON RESOLUTION VOLUME-COMPUTED TOMOGRAPHY

能够提供微观结构表征的仪器 医用级聚合物、织物和复合材料是建议 研究的长期目标。计算的1微米分辨率体积 测试样本的层析成像现在可以通过结合一个 NIST开发的X射线显微镜具有BIR的体积CT能力。微观 VCT将是开发新的医学材料的有价值的工具。 亚微米分辨率的NIST系统目前在 布鲁克海文同步加速器。经过适当的修改，它可以被改编 收集VCT数据集。与NIST合作，BIR将设计 并应用所需的修改和收集的VCT数据集 在BIR重建成三维密度图。一微米 分辨率将在测试对象和材料样品上进行演示。 虽然x射线显微镜目前被设计为在 同步辐射，第二阶段的研究工作将针对 对其进行修改和改进，以便与常规技术广泛使用 X射线源。

Instrumentation that can provide microstructural characterization of medical grade polymers, fabrics, and composite materials is the proposed research's long term goal. One micron resolution volume computed tomography of test specimens can now be demonstrated by combining an NIST-developed x-ray microscope with BIR's volume CT capability. Micro VCT will be a valuable tool in the development of new medical materials. The submicron resolution NIST system is currently in operation at the Brookhaven synchrotron. With suitable modifications, it can be adapted to collect VCT data sets. In collaboration with NIST, BIR will design and apply the required modifications and the collect VCT data sets for reconstruction into three dimensional density maps at BIR. One micron resolution will be demonstrated on test objects and material samples. While the x-ray microscope is currently designed for operation with synchrotron radiation, a Phase II research effort will be directed toward its modification and improvement for wide spread use with conventional x-ray sources.
