Fractional Laser Skin Treatment Using Diffractive Optics
Fractional laser skin treatment, also known as fractional photothermolysis, is a relatively new method of skin rejuvenation in which the targeted areas of the skin are precisely spaced out at a microscopic level. In between, some skin is left perfectly intact while other zones are laser-treated. The effect is visually comparable to pixels in digital images. The small spots of treated skin replace old destroyed cells with new healthy ones, and the untreated areas maintain the tissue’s ...

New Approaches to Traditional Fluorescence Illumination
Fluorescence microscopy presents an array of illumination challenges. Key among these is matching the spectrum of the light source to the fluorophore in the sample, to the bulb alignment and lifetime, and to the evenness of illumination. A new lamp...

State of the economy 2010
There’s a prodigious pachyderm in the parlor, but nobody is able to agree on just how big it is or whether it is about to rampage through the house. The beast, of course, is the Patient Protection and Affordable Care Act (The baby hanging onto...

Are Imaging Jobs Going Abroad?
Hospitals have begun to call on doctors in India, for example, for preliminary readings of computed tomography (CT), x-ray, ultrasound and other scans. Proponents argue that this allows reading of emergency scans in the middle of the night without...

Lab Chips Get Specific
After sometimes seeming like a solution in search of a problem, lab-on-a-chip technology may be finding its footing in application-specific incarnations, not in general-purpose devices. One key to its success is finding the right targets and better...
