The investigators will focus their research on fully developing the automated instrumentation capabilities of microscopic systems that offer the potential for quantifying the 3-D shape parameters, and changes in shape parameters over time, of microscopic-scale biological specimens. They plan to continue their program of studying diversity of complementary imaging modalities, including confocal microscopy, stereo microscopy, and conventional optical sectioning microscopy. The program of study will encompass microscopic data acquisition via various methods. The images obtained will be subjected to appropriate filtering schemes base on the physical principles of image formation to sharpen and improve image clarity in individual micrographs and to remove information spurious to that of the local specimen structure. The filtering techniques, which will require considerable analytic study in their development, will be specific to each optical system used. Finally, the aggregate local optical data will be assembled and analyzed via sophisticated numerical instrumentation techniques to reconstruct the 3-D structure of a given imaged specimen and to quantify its size and shape characteristics as it evolves over time. The methods developed will be implemented and evaluated on a broad range of specimen types, including stained and unstained single and multiple celled subjects. Several different tissue preparations will be used to study the time evolution of specimen morphology over time during various biological processes.

研究人员将把他们的研究重点放在充分开发显微系统的自动化仪器能力上，这将为量化微观尺度生物标本的3-D形状参数和形状参数随时间的变化提供可能性。他们计划继续研究互补成像方式的多样性，包括共焦显微镜、立体显微镜和传统光学切片显微镜。研究计划将包括通过各种方法获取微观数据。获得的图像将根据成像的物理原理经过适当的滤波方案，以锐化和提高个别显微照片中的图像清晰度，并去除与局部样品结构的信息虚假的信息。过滤技术的发展将需要大量的分析研究，这将针对所使用的每个光学系统而定。最后，聚合的局部光学数据将通过复杂的数字仪器技术进行组合和分析，以重建给定成像样本的三维结构，并量化其随时间演变的大小和形状特征。开发的方法将在广泛的标本类型上实施和评估，包括染色和未染色的单细胞和多细胞受试者。在不同的生物过程中，将使用几种不同的组织制剂来研究标本形态随时间的演变。
