 DESCRIPTION (provided by applicant): Funds are requested to purchase a VisualSonics Vevo 2100 research ultrasound imaging system for the Cardiovascular Phenotype Core at the University of Iowa. The Core was founded in 2002 with NIH funds. In the time since, the Core has provided about 20,000 imaging studies in mice and rats, and has introduced a number of novel methods for assessment of organ structure and function in vivo. In 2010, a Vevo 2100 system was purchased with NIH funds. Usage of that instrument has exceeded projections by > 50%; reaching 3113 studies in 2013. Recruitment of new NIH-funded faculty, whose research depends on animals housed in a pathogen-free barrier facility, will increase demands on the existing Vevo 2100 system beyond its capacity. Accommodation of new Users, along with existing Users, will incur significant hardship, expense, and compromise of experimental design unless an additional Vevo 2100 system is purchased. This request coincides with the launch of a new paradigm-shifting initiative by the University of Iowa Carver College of Medicine (UICCOM). The requested instrument will be housed and operated in the new Pappajohn Biomedical Discovery Building, which will open in June, 2014, at a cost of $147M. Two whole floors of that building will be devoted to research imaging, managed by the Iowa Institute for Biomedical Imaging (IIBI). Commensurate with this new vision, IIBI will provide state of the art space and infrastructure for the requested instrument without financial encumbrance. UICCOM will fund the instrument's service contract. The Cardiovascular Research Center will provide funds for faculty and technical personnel to operate the instrument. Together, the institution will provide $213,350 per year for operation of the requested instrument alone, in addition to space and infrastructure. The requested instrument will support the research of NIH-funded investigators in the fields of hypertension, vascular disease, cardiac arrhythmia, cardiomyopathy, and valvular heart disease. The Core will build on its track record of innovation and productivity, and on its history of training new imaging scientists.

 描述（由申请人提供）：申请资金用于购买爱荷华州大学心血管表型核心的VisualSonics Vevo 2100研究超声成像系统。该中心成立于2002年，由NIH资助。从那时起，核心已经提供了大约20，000个小鼠和大鼠的成像研究，并引入了许多用于评估体内器官结构和功能的新方法。2010年，用NIH的资金购买了Vevo 2100系统。该工具的使用超过预测50%以上; 2013年达到3 113项研究。招募新的NIH资助的教师，他们的研究依赖于动物安置在一个无病原体的屏障设施，将增加对现有的Vevo 2100系统的需求超出其能力。除非购买额外的Vevo 2100系统，否则新用户沿着现有用户的住宿将产生重大困难、费用和实验设计的妥协。这一要求与爱荷华州卡弗医学院（UICCOM）推出的一项新的范式转变计划不谋而合。所要求的仪器将被安置在新的Pappajohn生物医学发现大楼，将于2014年6月开放，成本为1.47亿美元。该大楼的两整层将用于研究成像，由爱荷华州生物医学成像研究所（IIBI）管理。与这一新的愿景相适应，IIBI将为所要求的仪器提供最先进的空间和基础设施，而无需财务负担。UICCOM将为仪器的服务合同提供资金。心血管研究中心将为教职员工和技术人员提供操作仪器的资金。该机构将共同努力， 每年提供213，350美元，除空间和基础设施外，仅用于所要求的仪器的运作。所要求的仪器将支持NIH资助的研究人员在高血压、血管疾病、心律失常、心肌病和心脏瓣膜病领域的研究。核心将建立在其创新和生产力的跟踪记录，以及其培训新的成像科学家的历史。
