Intelligent robotics is one of the technologies that has the potential to fundamentally alter society. From both an industrial and social perspective. “Smart perception” is a key concept that will drive this evolution toward intelligent robotics. With the continued advancements, we could see micro-sized cameras looking at every angle, depth, [...]
It’s the part of the eye exam everyone hates: the pupil-dilating eye drops. Your eyes remain blurry for several hours afterwards, often making the process inconvenient for both patient and doctor. The reason for the dilation is to keep the iris from constricting, and is used for routine examination and [...]
Biomedical engineers at Duke University have discovered a way to detect signs of cancer on a cell-by-cell basis using a technique that involves two lasers and a camera. The technique, using biomedical lasers and cameras, can assess an individual cell’s stiffness using patterns that appear within its internal structure. Several [...]
Optical imaging is a technique for non-invasively looking inside the body, as is done with x-rays. But, unlike x-rays, which use ionizing radiation, optical imaging uses visible light and the special properties of photons to obtain detailed images of organs and tissues as well as smaller structures including cells [...]
Safer lasers to map your cells could soon be in the offing – all thanks to the humble jellyfish. A combined team of researchers from Scotland and Germany has developed a way to create a polariton laser by using jellyfish proteins cultivated in E. coli cells. In their paper [...]
Neuroimaging or brain imaging is the use of various techniques to either directly or indirectly image the structure, function/pharmacology of the nervous system. It is a relatively new discipline within medicine, neuroscience, and psychology. Physicians who specialize in the performance and interpretation of neuroimaging in the clinical setting are [...]
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 [...]
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 [...]
