Medical Imaging

Deep Learning-based Analysis

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 locate an object or region […]

Neuroimaging With Machine Learning

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.

MRI Machine

MRI With Proton Beam

MR guidance is emerging as a powerful tool for real-time monitoring of radiation treatments, offering excellent soft-tissue contrast and the ability to track intra-fractional tumor motion. Hybrid devices for MR-guided photon-based radiotherapy are now in clinical use. But to date, no such combined system exists for proton therapy.

Transmission Electron Microscope

Transmission Electron Microscope

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 electrons with the sample […]

Metalaneses

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

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

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

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

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.
