New Hand-held Ultrasound Scanner
NIH funded research resulted in the development of the Vscan, a palm-sized ultrasound scanner with color-flow Doppler that can quickly identify blood flow or heart problems. It can be used at the bedside, in an ambulance, or in low resource settings and is currently being sold in 100 countries.

In the first segment, study participant Kent Stephenson does voluntary training with spinal stimulation. In the last segment, study participant Rob Summers tosses a medicine ball with research staff member Paul Criscola. All studies were conducted at the Human Locomotion Research Center laboratory, a part of the University of Louisville's Kentucky Spinal Cord Injury Research Center, Frazier Rehab Institute, Louisville Kentucky.
Seeking Clues to Human Brain Development by Observing C. elegans
Dr. Hari Shroff, Chief of NIBIB's High Resolution Optical Imaging laboratory, uses SPIM (selective plane illumination microscopy) techniques to study neural development in a transparent worm called C. elegans. This search may reveal clues to the development of the human brain and nervous system.
Glow Worm: Green Fluorescent Proteins light up C. elegans
Dr. Hari Shroff, Chief of NIBIB's Section on High Resolution Optical Imaging lab, uses high-powered microscopes and green fluorescing proteins developed by Dr. George Patterson's Section on Biophotonics lab to observe the mitosis and development of a C. elegans embryo. Images are made using SPIM, which is selective plane illumination microscopy.
Meet Micro Chip!
Don't miss hip, hip Micro Chip in his debut music video. Learn what this cool point-of-care technology can reveal about your biology! The original microchip used for this animation was developed by NIBIB's by Dr. Terry Phillips and Edward Wellner for assessment and research of the human immune system. This video also highlights the circulating tumor cell microchip developed by NIBIB grantees and Stand Up to Cancer Dream Team members, Drs. Daniel Haber and Mehmet Toner of Massachusetts General Hospital.
5-D Imaging of the Heart
Three spatial dimensions show the cardiac anatomy. The 4th dimension is time as the heart is shown beating throughout successive cardiac cycles. The 5th dimension is the mapping of the electrical activation pattern that causes contraction of the left ventricular chamber. All of these signals are registered in exact synchrony to provide 5-D image. Richard A. Robb, Ph.D., c. 2006 Mayo Clinic College of Medicine
3-D Reconstruction of the Rat Small Intestines for Modeling Nutrient Transport
To provide the surface boundary conditions for computer simulations of macro-micro mixing motions of the small intestine, we carry out dynamic imaging of gut motility using magnetic resonance imaging of the rat small intestines. Shown is a three-dimensional reconstruction of stacked multi-slice static images of the rat stomach, a rather long duodenum and a tangled jejunum and ileum. From these reconstructions we select sites for time-resolved single-slice imaging to obtain boundary conditions for the modeling. This research was funded by the National Science Foundation, as part of the Interagency Modeling and Analysis Group's (IMAG) Multiscale Modeling Initiative. This initiative is administered by the National Institute of Biomedical Imaging and Bioengineering (NIBIB), a part of the National Institutes of Health. James G. Brasseur, Ph.D. and Andrew G.
