Thyroid and Salivary Gland Tumor Detection Salivary gland tumors and thyroid tumors are both considered head and neck cancers, so they are often grouped together when discussing diagnoses or treatments. ...

High Resolution Microscopy Image quality in high-resolution optical microscopy is predominately restricted by the diffraction limit– a fundamental consequence of using lenses.  High-resolution ...

Cardiovascular Disease and Photoacoustic Imaging Cardiovascular diseases (CVDs) are the number one cause of death in the world, accounting for 31% of all deaths. This class of diseases includes heart ...

Imaging tools help us see into the world that is not possible with our naked eyes. It was with the invention of the microscope and the telescope that big frontiers in science were reached. We unlocked the ...

Non-linear techniques in photonics have opened up new avenues for sensing and manipulating materials. In the 1960s, non-linear techniques were used to discover multiphoton absorption processes in ...

X-Rays and Imaging We commonly associate x-ray imaging with hospitals and broken bones, but why are x-rays the chosen source of radiation instead of visible light or electron beams? The high initial energy ...

A research team from the Military Technical College and from Cairo University in Cairo, Egypt have developed a fluorescence hyper-spectral imaging system which can be employed for diagnosis and detection ...

  Developing a clear characterization of a tumor’s microenvironment is imperative in understanding its progress. A new approach to determining cancer’s development involves a thorough study of ...

Previously, we discussed a technique for producing high resolution maps of neural activity in the brain called Optical Recording of Intrinsic Signal, or ORIS.  Conventional methods for performing ORIS ...

Previously, we discussed how visible light in combination with implantable optical sensors was used to map epileptic neural activity and localize focal seizures on the surface of the brain.  Scientists at ...
