The next time your doctor says he can look right through you, he may be speaking literally and not just figuratively, especially if your doctor is George Stetten, a biomedical engineer at the University of Pittsburgh. Although doctors sometimes use ultrasound for looking inside patients, current technology requires that the doctors look away from the patient at an ultrasound display. Stetten says the result is a displaced sense of hand-eye coordination. "The difficulty is developing a natural way to visually merge ultrasound images with the real world," says Stetten. His "sonic flashlight" uses a process called tomographic reflection. By strategically positioning an ultrasound scanner and the ultrasound display on opposite sides of a half-silvered translucent mirror, he simultaneously sees the patient and the ultrasound image in perfect alignment with the body. Stetten says that he merges the virtual image in three dimensions with the interior of the patient. This simultaneous viewing makes the ultrasound image appear to occupy the same physical space as the body being imaged. The effect relies on precise geometric relationships between the ultrasound slice scanned, the monitor displaying the slice, and the mirror. "The reflected image is optically indistinguishable from the corresponding space within the patient," explains Stetten. For more information, call (412) 624-7762.
Lithium-ion battery prices will drop rapidly over the next 10 years, setting the stage for plug-in vehicles to reach 5%-10% of total automotive sales by the mid- to late-2020s, according to a new study.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
A recent Design News-exclusive study proves that engineering professionals are at the very forefront of this push into the future and making direct financial, performance, and value impact on their organizations by being personally involved or final decision-makers on automation solution and component choices.
