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. Tissue Microdissection for Molecular Analysis of Disease and Normal States (LCM, TAM, xMD, TAM, fTAM); NICHD, NIDA, NIBIB, NCI, NIMH. 2.
