      OCT angiography moves beyond ophthalmic applications

      OCT angiography moves beyond ophthalmic applications 10 May 2016 Wasatch Photonics platform brings the technique to a broader range of bioimaging uses. OCT angiography: structural and blood flow information. A new imaging platform launched by Wasatch Photonics aims to widen the range of applications for high-resolution optical coherence tomography angiography, and enhance the versatility of the technique for both researchers and OEM manufacturers. OCT angiography has already made inroads into clinical ophthalmology, where its non-invasive ability to provide both structural and blood-flow information via functional OCT without the need for fluorescent markers offers an attractive way to map retinal and ...

    2. OCT variant looks good for vascular imaging

      OCT variant looks good for vascular imaging

      Researchers in New York have shown that a variation of optical coherence tomography (OCT) is able to tell melanomas apart from other skin lesions, by imaging the patterns of blood vessels that surround them. The small, early-stage study suggests that speckle-variance (sv) OCT could become a useful clinical tool for quickly identifying the most dangerous form of skin cancer, although a larger clinical trial of the technique will be needed to prove its utility first. Writing in the open access journal Dermatology Online , Orit Markowitz and colleagues looked at two pairs of malignant and benign lesions that are typically difficult ...

      Laser Zentrum Hannover develops presbyopia laser surgery model

      A research effort involving Laser Zentrum Hannover (LZH) in Germany is developing a new, laser-based treatment for presbyopia – the condition that impacts near vision in people from around the age of 40 onwards. At the moment presbyopia – caused by the age-related stiffening of the lens in those affected – is usually treated with simple solutions like reading or bifocal glasses, with multi-focal contact lenses from the likes of Bausch + Lomb becoming available more recently. Some laser procedures have also been developed, but if successful the LZH-led project could lead to a "gentle" new femtosecond laser technique that makes tiny cuts in ...

      Zeiss Meditec sales cruise past €1BN

      Carl Zeiss Meditec , the healthcare equipment division of the German optics giant Zeiss, has smashed its annual revenue target after posting sales in excess of €1 billion for the first time. At €1.04 billion, the publicly listed company’s revenues for the year ending September 30 were up 14 per cent on the previous 12 months . And although the weak euro currency accounts for nearly half of that growth rate, the result still saw the company’s stock price rise close to a 15-year high on the Frankfurt exchange. Leading the charge was Meditec’s surgical ophthalmology division, where ...

      Compact Imaging sees OCT in smartphones, tablets and wearables.

      The capabilities of optical coherence tomography (OCT) as a non-contact imaging technique have become readily apparent since it first made inroads into ophthalmology clinics in the 1990s, but the inherent size and complexity of the instrumental platforms have conspired to keep it out of lower-cost or consumer-based applications. That may now be about to change, with the development of a new OCT platform christened multiple reference OCT (MR-OCT) by Compact Imaging , a California start-up with strong Irish connections. The company believes MR-OCT offers a way to bring the technique's biometric and imaging capabilities to applications where cost and form-factor ...

      Zeiss Meditec sales hit by currency fluctuations

      Shares in Carl Zeiss Meditec , the clinical wing of the optics and microscopy giant, dropped in value by around 6 per cent on the Frankfurt stock exchange after the company just missed its annual sales target. For the year ending September 30, the Germany-headquartered firm delivered revenues of €909 million. That was up very slightly on the figure of €906 million for the previous year, but below the range of €910 million to €940 million estimated back in May – something blamed largely on currency effects. CEO Ludwin Monz said of the result: “In spite of adverse currency trends and to ...

      Imaging of blood flow reveals effects of drug use

      maging techniques that can reveal the direct effects of drugs on blood flow in the brain are a key to understanding the physiological underpinnings of drug abuse, and hence a potential route to superior treatments. Optical coherence Doppler tomography (ODT) is one promising answer, able to deliver quantitative visual information about the behavior of blood vessels, and provide valuable functional data about what happens to them under different stimuli and conditions. Researchers at Stony Brook University , New York, and the National Institutes of Health have now used the technique to image the effect of cocaine on cerebral blood flow in ...
