Medical Imaging Lenses and Lens Design for precision medical applications.
Short Wave Infrared (SWIR) lenses have become an indispensable tool in various high-tech fields including surveillance, medical, surgery and pollution detection.
The recent research on medical proton imaging is by and large motivated by the desire to gather information using a less invasive source such as X-rays. With the use of a proton microscope, it is possible to image biological tissue without leaving any radiating material behind in the tissues of [...]
Radiological x-rays, ultrasounds and NMR’s are all forms of medical imaging that have traditionally required the flexibility of the human eye to detect anomalies within the human body. Since a computer is confused by busy backgrounds and image quality issues, it is difficult for a traditional machine vision algorithm to [...]
Studying the human mind is challenging. Currently, most human brain studies are limited to non-invasive approaches, such as magnetic resonance imaging (MRI). This limits the examination of the human brain at the cellular level, which may offer novel insights into the development and potential treatment of various neurological diseases. [...]
TEM, or Transmission electron microscopy (also sometimes conventional transmission electron microscopy or CTEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of [...]
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. [...]
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 [...]
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 [...]
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 [...]
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 [...]
