Medical Imaging Lens Assemblies News

Metalenses
While traditional lens is made from glass, metalenses use flat surfaces made up of nanostructures to focus light. These simple, flat surface lenses could replace bulky, curved lenses currently used in optical devices.
Electron Microscope
The electron microscope is a type of microscope that uses a beam of electrons to create an image of the specimen. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail.
3D Medical Imaging
From the early days of CT scanners and mammography devices, medical imaging has come a long way. With 3D medical imaging, healthcare professionals can now access new resolutions, angles, and details to help them gain a better understanding of their patient, all while cutting back on the dosage of radiation used to gather the images.
Cone-beam Imaging Scanners
Cone-beam imaging CT (CBCT) scanners offer the advantages of being compact in size, less costly, and more portable than multidetector CT systems. Image quality, however, is often impacted by artifacts such as streaking or shading, associated with cone-beam effects and/or nonuniformity in image quality near the ends of the field-of-view (FOV).
Metalens – Technology For The Future
Glass-based optical lenses are used in multiple applications.  From the camera in a cell phone to a sophisticated, professional camera, to microscopes and other imaging devices used in the medical field – glass lenses are the standard. Today’s lenses are bulky and resist miniaturization. Next-generation technologies, in relationship to cameras or microscopes, require lenses made […]
Raman Optical Technology
Using Raman optical technology, scientists at the University of Twente in The Netherlands can now produce images of brain tissue that is affected by Alzheimer’s disease. The images include the surrounding areas that are already showing changes.
Tunable Lens - Changing The Way Eyes Are Viewed
Researchers have developed the first instrument that will provide a detailed image of the entire eye. Incorporating a lens that changes optical parameters in response to electric currents, the radically new technology can produce higher quality images than currently available. Combining optical coherence tomography and an electrically actuated tunable lens will change the way medical […]
Optical Tweezers
Originally called ‘single-beam gradient force trap’, optical tweezers are scientific instruments that use a highly focused laser beam to provide an attractive, or repulsive force, depending on the refractive index mismatch to physically hold and move microscopic dielectric objects similar to tweezers. Optical tweezers have been particularly successful in studying a variety of biological systems […]
Neuroimaging And Alzheimer’s
Currently, diagnosing Alzheimer’s relies largely on documentation of any mental decline. However, when diagnosing Alzheimer’s in this way, it has already caused severe brain damage in individuals. What if we could diagnose Alzheimer’s before symptoms started? It is increasingly clear that by the time a typical AD patient comes to diagnosis atrophy is well established. […]
Atomic Force Microscope
You may have seen it on CSI: The star examines hair from a crime scene and concludes its color or texture looks like the defendant’s hair, or maybe his dog’s. Case closed. But, looks can be deceiving, as well as vague and subjective. According to Frank DelRio, and engineer at the National Institute of Standards […]
Biophotonic Technology And HIV
Biophotonic technology plays a key role in providing the most effective, lowest-cost approaches for diagnosing, treating, and preventing disease and maintaining a healthy U.S. citizenry.
Retina Camera – No Dilation Required
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 to photograph the back of […]
The Endoscope Capsule – A Camera in a Pill
Pop this pill, and eight hours later, doctors can examine a high-resolution video of your intestines for tumors and other problems, thanks to a new spinning pill camera that captures images in 360 degrees. Developed by the Japanese RF System Lab, the Sayaka endoscope capsule entered the U.S. market in 2008. An endoscope is a […]
Scanning Fiber Endoscope
Strokes and heart attacks often strike without warning. However, a unique application of a medical camera, a scanning fiber endoscope (SFE), could one day help physicians know who is at risk for a cardiovascular event by providing a better view of potential problem areas. The scanning fiber endoscope (SFE) acquires high-quality images of atherosclerotic lesions […]
Cardiac MRI Predicts Future Heart Failure
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 heart. Researchers have now found that […]
Differentiating Skin with IR Detection
More and more biometric systems are being used for security in public places, buildings such as airports, or security-related areas like data centers. The greater the proliferation of such systems, the greater the probability of methods designed to circumvent or outwit them.  This, in turn, requires the development of even more reliable security systems. Unfortunately, […]
Prostate Cancer Surgery Aided By Light Reflectance Spectroscopy
The National Cancer Institute reports that prostate cancer is the most common cancer in men, second only to skin cancer. Following lung cancer, prostate cancer is the second leading cause of cancer-related deaths in men in the United States. Light reflectance spectroscopy has been used by surgeons during prostate cancer procedures as a way to […]
Heart Condition Diagnosis More Reliable With Optoacoustic Sensor
Optical Interferometry is the technology that could enable ultrasonic methods to be used internally on patients to capture information about their heart and the heart tissue. Prior to this technology, ultrasounds would be used externally to examine a patient’s heart. The reason for this is that piezo electronic components that were necessary for the technology […]
Considerations For Ophthalmic Surgical Laser Systems
The developments of laser systems for eye surgeries have shown great success in the eye surgical field. It was in the 1990s when researchers developed a femtosecond laser that was able to generate ultra-short laser pulses. Because of the robust laser sources and the shortened pulse lengths this laser replaced the mode-locked dye lasers which […]
Technology Makes Endoscopic Procedures Less Uncomfortable
National University of Singapore researchers have developed an endoscopic probe that can deliver adjustable-focus capabilities in a smaller, slimmer package; the design will make the procedure less uncomfortable for the patient. The endoscopic probe has a miniature, solid tunable-lens technology that allows for a compact optical zoom and autofocus. Surgeons using the probe can easily […]
Treatment For Paralyzed Muscles Found In Light-Activated Neurons
A technique developed by researchers at University College in London has been found to potentially restore the function of muscles afflicted by motor neuron diseases or spinal cord injuries. Researchers found that transplanting motor neurons created from stem cells into injured nerve branches in a patient had the potential to restore muscle movement. This laser […]
Adaptive Optics Show Cells In The Eye
Optics techniques have been developed by researchers at the University of Illinois that allow ophthalmologists to see the individual cells in the eye ball at the back of a patient’s eye. The benefit of this adaptive optics technique gives the doctor a detailed view of the eye’s blood vessels, cells and the nerves at the […]
Medical Lenses And Microscopy Illuminates Cancers
Discovering cancer cells and cancerous tissues as soon as medically possibly bodes best for the patient to receive a diagnosis and treatment that brings with it the best possible outcome.
