DEVELOPMENT OF A CONSTANT-VOLUME VENTILATOR FOR SMALL ANIMALS

这个子项目是利用资源的许多研究子项目之一。 由NIH/NCRR资助的中心拨款提供。对子项目的主要支持 子项目的首席调查员可能是由其他来源提供的， 包括美国国立卫生研究院的其他来源。为子项目列出的总成本可能 表示该子项目使用的中心基础设施的估计数量， 不是由NCRR赠款提供给次级项目或次级项目工作人员的直接资金。 在小动物身上进行超极化气体磁共振成像(以及其他研究)通常需要专用的呼吸机系统。昂贵的稀有同位素(如3He和129Xe)的使用表明，有必要在这些气体用于成像后回收这些气体，以最大限度地降低成本。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Hyperpolarized gas MR imaging in small animals (and other studies as well) have generally required a dedicated ventilator system. The use of expensive rare isotopes (such as 3He and 129Xe) present a need to miinimize cost by recycling these gases after they have been used for imaging.
