Photon-counting CT (PCCT) is the mainstay of multi-spectral imaging, enabling quantitative tissue characterization. In radiation oncology, cone-beam CT is used daily for image-guided and ...

Chop and change The top panel shows a photon (represented as a wave) being reflected from a mirror. The wave is incident from left to right with the solid blue line showing the portion of the wave ...

Edinburgh-based semiconductor company Singular Photonics has launched Litavis, a new image sensor designed to ...

The world of laser scanning microscopy is quickly evolving, thanks to the advent of fast and compact detector arrays. These arrays replace the typical single-element detector of traditional confocal ...

The first randomized trial to compare photon- and proton-based radiation therapy for breast cancer finds that patients report equally strong health-related quality of life with either treatment.

The vast majority of modern quantum technologies—from quantum cryptography to the quantum internet to the quantum computer—rely on one essential element: the transmission of photons. Two qubits (two ...

Scientists reveal how a record-breaking photon from the BOAT gamma-ray burst may have survived its journey across billions of light-years to Earth.

Forbes contributors publish independent expert analyses and insights. I write about biodiversity and the hidden quirks of the natural world. Research reveals how close human vision comes to sensing ...

Beauty and mystery—it is hard to imagine a more alluring combination, and this is precisely what we encounter when we observe phenomena in the nanoworld. But are we really sure that observations made ...
