      PROSCOPE project aims for early-stage bowel cancer detection

      Multimodal platform should allow cellular-level colon imaging in real-time. Improving diagnosis: PROSCOPE A project funded by the EU's Horizon 2020 program is on course to develop a new imaging system for the diagnosis of bowel cancer. PROSCOPE , officially titled "Point-of-care instrument for diagnosis and image-guided intervention of colorectal cancer," was launched in 2020 and backed by €6 million of EU funding. The project has now carried out an 18-month formal review, confirming that its research program is on target to help reduce the 160,000 deaths and €9 billion in healthcare costs associated with the disease. "Currently, only 14 ...

      'World-first' treatment of patient with high-frequency OCT for cardiology intervention

      A partnership of Tampa General Hospital (TGH) and University of South Florida’s Health Interventional Cardiology Group have adopted a new intravascular imaging technology and performed the first such procedure in the world. The new intravascular technology, called High Frequency Optical Coherence Tomography (HF-OCT), was recently performed on a patient with critical coronary artery disease, which the partners say, “was the first such successfully treated in the world.” Tampa General has been an early adopter of intravascular imaging for coronary intervention and continues to seek the newest and best technology. The team has incorporated intravascular ultrasound (IVUS) and intravascular optical ...

      Photonics West 2021: OCT makes further biomedical breakthroughs

      Optical coherence tomography is a real success story in biomedical optics technology, a true bench-to-bedside path." So commented Michael Kaschke, former Chairman of Zeiss for a decade and as of November 2019 Chairman of the KIT Supervisory Board , when he addressed the SPIE Photonics West Digital Forum on the topic of OCT's past success and likely future applications. "At the World Ophthalmology Congress in 2009 I was asked what technologies I believed would play a key role in the following decade," said Kaschke. "I said that ubiquitous use of OCT was one, along with multifocal lenses, femtosecond lasers in ...

      Laser scanning reflection-matrix microscopy sees inside intact mouse skull

      Visualizing tissues and neurons inside an animal's skull has long been a challenge for biophotonics techniques, thanks to the skull's thickness and the complex structures inside. Approaches to this problem have included the use of endoscopic platforms in brain imaging, two-photon and three-photon microscopy of small animals, and for surgical purposes the creation of a transparent window in the skull itself. A team at the Institute for Basic Science ( IBS ) in Daejeon, South Korea, has now developed a new approach to tackling the optical aberrations involved in imaging through an intact skull, and tested the system on a ...

      OCT angiography improves views of retina blood flow

      Projects from Boston and Portland could help translation of OCTA into clinics. Retina blood flow: vital for diagnosis Optical coherence tomography angiography (OCTA) is a promising technique for imaging of blood vessels, in which sequential OCT scans of the same tissue cross-section reveal the sites of blood flow within those tissues, and can allow the blood oxygen content to be calculated. Examination of the retina is one promising application area for OCTA, thanks partly to the widespread adoption of conventional OCT within ophthalmology and its established place in clinical workflows. Two recent projects have published findings that could assist the ...

    8. Heartbeat elastography allows assessment of cornea condition

      Heartbeat elastography allows assessment of cornea condition

      Several diseases of the cornea, such as corneal dystrophy and keratoconus, lead to underlying changes in a cornea's intrinsic biomechanical properties as well as the inherent cellular damage. Measuring those biomechanical markers could be a valuable tool for monitoring and detecting the diseases, especially if the technique can be a non-contact method. Non-invasive measurement methods are inherently likely to be best suited for eventual translation into clinics, and for reducing patient discomfort. Optical coherence elastography (OCE), in which optical coherence tomography is used to image tissue while it is under some form of transient local mechanical deformation and subsequent ...

      OCT links blood vessels to melanoma type

      A clinical study of malignant melanoma suggests that optical imaging of the most aggressive form of skin cancer could yield a faster assessment of particularly dangerous tumors. According to the UK-based optical coherence tomography (OCT) hardware developer Michelson Diagnostics , whose equipment was used in the study by four European dermatology research groups, the technique could offer a “short-cut” to identifying advanced cancers that have begun to spread. That might provide patients with a more aggressive or advanced tumor access to appropriate treatment more quickly, while those with less virulent melanomas could be spared invasive and expensive sentinel lymph-node biopsies that ...

      Hamamatsu develops bright supercontinuum source

      Hamamatsu Photonics has developed a supercontinuum light source, also known the SC light source, that produces higher brightness – approximately 1000 times higher than the company’s own range of xenon lamps. At the same time, the SC source maintains the high stability equivalent to that of xenon lamps by optimizing output conditions and also using a high nonlinear optical fiber as its nonlinear optical material. This source is targeting the market for measuring the complex structure of semiconductor optical measurements. The company added that its official commercial release will be in the spring of 2019. The new SC light source ...

      Wavefront shaping promises all-in-one laser cataract procedure

      Photo-fragmentation Venture-backed French startup company Keranova says that its femtosecond laser system will “revolutionize” the field of cataract operations, by providing surgeons with a single tool that can be used for the entire procedure. The St. Etienne firm says that it has found a way to improve on the current generation of ultrafast laser equipment, which is unable to complete the crucial lens photo-fragmentation step quickly enough. Surgical disappointment Presenting the company’s technology during an industry session at this week’s SPIE Photonics Europe event in Strasbourg, Keranova’s scientific director Aurélien Bernard explained that despite the introduction ...

      OCE reveals tissue damage caused by heart attacks

      A heart attack, or myocardial infarction (MI), can cause considerable damage to the tissues of the heart, and a better understanding of that damage would be a valuable step towards improved treatment and therapy after the attack. Researchers at the University of Houston have developed a technique based on optical coherence elastography (OCE) that could be used for biomechanical characterization of MI, and be a useful tool to study heart repair. The work was published in Biomedical Optics Express . "About one million people suffer heart attacks every year, and there is currently no cure for the resulting cardiac tissue scarring ...

      OCT with tunable lens allows whole-eye imaging

      Optical coherence tomography has become a standard technique in ophthalmology, thanks to its easy fit with clinical workflows and the ability to image particular zones of the eye, such as the anterior chamber and the cornea. Use of the same technique to image the whole eye has proved challenging. OCT's limited imaging depth can be improved though Fourier domain methods and use of modern swept-source laser sources, but the optics of the eye prevent the focusing of light on both the anterior chamber and the retina simultaneously without sacrificing resolution. A project from Poland's Nicolaus Copernicus University and ...

      Sales into G&H’s other target market sector – life sciences – have risen at a slower rate, but at £9.6 million were still up nearly 10 per cent on the prior year. Key applications here include optical coherence tomography (OCT), laser surgery and microscopy, with Webster writing: “Despite the increase in revenue the [life sciences] profit did decline year on year, which is primarily due to the investments made into future capabilities. Though life sciences is a relatively small sector for G&H, we see this as a strategically important one going forward.
