Signal Processing And Instrumentation Section

信号处理和仪器科（SPIS）的研究和开发活动是与NIH研究所的科学家合作进行的，需要开发生物医学实验室和临床研究系统、仪器和方法。这些合作中的大多数都需要新颖的方法和设计，而这些方法和设计只有很少的既定标准或技术知识。SPIS员工在工程研发的各个阶段都有丰富的技术经验。SPIS的工作人员与其合作者一起审查临床和生物医学科学，以制定项目规格。SPIS工作人员评估理论和实践限制，考虑商业上可用的技术，最后提出各种解决方案。SPIS的职责通常是继续动手设计、实施、测试、安装、培训、文档和定制研究系统或方法的生产。过去和目前的合作项目，以及相关的研究包括：

The research and development activities of the Signal Processing and Instrumentation Section (SPIS) are collaborative efforts with NIH Institute scientists that require the development of biomedical laboratory and clinical research systems, instrumentation, and methodologies. The majority of these collaborations require novel approaches and designs for which there are minimal established criteria or technical knowledge. SPIS staff have in-depth technical experience in all phases of engineering research and development. With their collaborators, SPIS staff review the clinical and biomedical sciences to formulate project specifications. SPIS staff evaluate the theoretical and practical constraints, consider commercially available technologies, and finally propose various solutions. SPIS responsibilities often continue with the hands-on design, implementation, testing, installation, training, documentation, and production of a custom research system or methodology. Example past and current collaborative projects, as well as associated research studies include: 1.
