Simply put, a portable Ultrasound Machine is a smaller, lightweight version of their predecessors. In most cases, they can be carried by hand, and in some cases, run on battery power alone. The first portable ultrasound machines arrived in the early 1980s but battery powered systems that could be [...]
To ensure reliability and safety, the developers of medical equipment that use laser technology know they need to be careful when they select the optical components. High power density and narrow wavelength range lasers bring with them problems that are not always found in other optical design. Choosing the [...]
As the automated manufacturing environment continues to evolve, the ability to analyze high-speed processes in order to increase quality and efficiency, along with the ability to identify and resolve immediate manufacturing line problems is essential. Factory floor personnel are required to accurately and quickly analyze and adjust complex electro-mechanical [...]
Vision-based face detection and recognition is one of the most rapidly growing research areas in computer vision and robotics and is widely used in several human related applications. However, vision-based face detection and recognition has been shown to be effective only under normal illumination conditions. In developing an algorithm [...]
In the late twentieth century, mankind made quantum leaps in its knowledge of the universe. Progress is underway to map the entire universe—with new insights into the vast unknown. In 1986, a significant leap in the science of astronomy and astrophysics occurred, introducing a new frontier: Positions of galaxy [...]
When you’re leaving the house or the office, what is one of the items you never leave home without? If you’re like most people, your smart phone is never far from your reach – whether in a handbag or a suit coat pocket. Regardless of whether you carry a [...]
Heat-generated plasmonic nanoparticles, with their potential use as cancer-killing agents, have seen positive results in both in vitro and in vivo studies, researchers say. Through the use of a single-particle and PET (positron emission tomography) -based platforms have allowed researchers from the University of Copenhagen to quantify the “photothermal [...]
Everyone has seen them - surveyors at a construction site or along a highway pointing what looks like a small telescope at a target. It is a small telescope, but they are not just looking at the scenery. Chances are, the surveyors are using a theodolite or transit to [...]
According to research presented at the British Cardiovascular Conference in Manchester, England, the amount a heart ‘bleeds’ following a heart attack can predict the severity of future heart failure. Over 40 percent of people who suffer from a heart attack will be affected by bleeding, or bruising in the [...]
Hyperspectral imaging, like other spectral imaging, collects and processes information from across the electromagnetic spectrum. It combines the power of digital imaging and spectroscopy. For each pixel in an image, a hyperspectral camera acquires the light intensity (radiance) for a large number (typically a few tens to several hundred) [...]
