UPGRADE RESEARCH IMAGE ANALYSIS LAB

亨利福特健康系统参与了各种NIH研究项目，这些项目需要极其密集的计算任务。这些研究项目分为几个类别：1)图像合成、图像处理、图像模式识别和定量图像分析，特别是涉及三维（空间）、四维（空间和时间）或多维（空间、时间和多光谱或多参数）数据集的应用；2)利用三维和四维有限元计算的建模技术；3 .三维图像重建。目前，亨利福特健康系统中唯一具有多处理器能力和任何计算能力的计算机系统是带有MVX加速器的SUN 4/490。在图像分析实验室该系统与医院的以太网接口，这是图像传输和远程工作站和x终端使用的要求。这个系统的一个主要问题是SUN不再支持MVX。硬件故障将危及图像分析实验室中计算资源的重要部分。本提案的目的是升级亨利福特医院的研究图像分析实验室，使我们能够以高效的方式提供大型多维数据集所需的计算能力和速度，以及数据存档，从而提供有效的研究环境。研究图像分析实验室包含一个连接到医院以太网的本地以太网，该以太网为多个用户以及来自成像设备和其他非图像研究数据集的图像数据集提供访问。这一升级将提供必要的计算能力和数据存档能力，使多项调查能够在多维数据集上实现研究目标，否则他们将难以在个人基础上证明这一点。

Henry Ford Health Systems is involved in a variety of NIH research projects that require extremely computationally intensive tasks. These research projects fall into several categories: 1) Image synthesis, image processing, image patter recognition, and quantitative image analysis, this is particularly true in applications involving three- dimensional (spatial), four-dimensional (spatial and temporal) or multiple-dimensional (spatial, temporal, and multi-spectral or multi- parameter) data sets; 2) Modeling techniques utilizing three and four dimensional finite element calculations; and 3( Three dimensional image reconstruction. At the present time the only computer system available in the Henry Ford Health System with multi-processor capabilities and any computational power is a SUN 4/490 with a MVX accelerator. in the Image Analysis Laboratory. This system is interfaced to the hospital's Ethernet network which is a requirement for the transfer of images and the use of remote workstations and X-terminals. A major problem with this system is that the MVX is no longer supported by SUN. A hardware failure would jeopardize significant portions of the computational resources in the Image Analysis Laboratory. The objective of this proposal is to upgrade the research Image Analysis Laboratory at Henry Ford Hospital so that we can provide the computational power and speed, and data archiving that is required on large multi-dimensional data sets in an efficient manner so as to provide an effective research environment. The research Image Analysis Laboratory contains a local Ethernet network which is bridged to the Hospital's Ethernet which provides access to multiple users as well as image data sets from imaging devices and other non image research data sets. The upgrade will provide the necessary computational power and data archiving capabilities necessary for multiple investigations to carry out research objectives on multi-dimensional data sets, which otherwise they would have difficulty justifying on an individual basis.
