The National Institute of Biomedical Imaging and Bioengineering (NIBIB), the
National Heart, Lung, and Blood Institute (NHLBI), the National Institute of
Environmental Health Sciences (NIEHS), the National Center for Research
Resources (NCRR), the National Institute of Diabetes and Digestive and Kidney
Diseases (NIDDK), and the National Institute of Neurological Disorders and
Stroke (NINDS) invite grant applications for Small Business Innovation
Research (SBIR) and Small Business Technology Transfer (STTR) awards to
support research and development of small animal imaging devices and methods
that can be applied broadly to research on diverse biological or disease
processes. A similar Request for Applications (RFA) for small animal imaging
research and development to be supported by individual Research Project Grant
(R01) awards can be found at

The primary focus of this Program Announcement (PA) is research and
development related to devices, methods, and imaging agents for the
investigation of biological and disease processes in small animals. The
integration of systems and methods with complementary imaging and/or
spectroscopy modalities is also included as appropriate to provide anatomic,
physiologic, metabolic, and molecular-level information in small animal
models of disease.
The motivation for this PA is that recent discoveries in genomics and
molecular and cell biology have led to the development and wide use of small
animal models of human disease. One of the limitations with the use of these
models is the need to sacrifice large numbers of animals for ex vivo tissue
and molecular analysis. Imaging instrumentation and methods that permit
imaging on the scale of small animals offer an opportunity to address this
problem by enabling noninvasive investigations of biological processes in
vivo. This capability provides the potential for longitudinal studies in the
same animal. The coupling of animal models of human disease with advances in
imaging technology presents an extraordinary opportunity for biomedical
imaging to play an important role in the early detection, diagnosis, and
treatment of disease. Several dedicated small animal imaging systems have
been developed and a few commercialized, although technological hurdles still
exist that limit the realization of the full potential of small animal
imaging for biomedical research and drug development. Progress is needed to
improve throughput, sensitivity, and spatial and temporal resolution of small
animal imaging devices, to provide quantitative information through improved
reconstruction methods that incorporate models of physical effects, and to
provide improved methods for system validation. System optimization
incorporating the design of molecular probes that serve as links to
particular biological processes in vivo is also a focus. Further improvements
in system design, image processing and analysis software, and data sharing
technology, coupled with improvements and innovations in animal handling
techniques during imaging, are needed to make small animal imaging technology
more accessible to molecular biologists and pharmaceutical scientists
desiring to use animal models as tools for biomedical research and drug
discovery and development.
