Cryo-electron tomography is an emerging method for three-dimensional (3D) imaging that bridges the gap between analyzing protein structure by X-ray crystallography and intact bacterial structure by ...

For patients with CAD, coronary computed tomography angiography fractional flow reserve (FFR-CT) is prognostic for adverse outcomes.

Determining an unknown signal from a set of measurements is a fundamental problem in science and engineering. However, as the number of free parameters defining the signal increases, its tomographic ...

Cryo-electron tomography (cryo-ET) can provide invaluable insights into subcellular structures in their native environment at ...

Diagnostic imaging has been a widely used tool in the detection and treatment of various diseases. Dual-energy computed tomography (DECT) is an emerging imaging technique that combines information ...

Olivera Ciraj Bjelac, IAEA Department of Nuclear Sciences and Applications To support hospitals and specialists around the world in meeting their safety standards requirements, the IAEA has produced a ...

» Does the patient exposure from a CT procedure depend on the number of slices? Before answering this question, let’s compare two radiation quantities involved. First, dose, or absorbed dose, ...

Positron-emission tomography (PET) is a noninvasive imaging technique that exploits the unique decay physics of positron-emitting isotopes. The isotopes of oxygen, carbon, nitrogen, and fluorine have ...

“Our results demonstrate that texture analysis can uncover minute retinal changes long before diabetic retinopathy becomes ...

It is said that every rose has its thorn, but technically speaking, roses have prickles. Prickles are derived from the epidermis of the plant, whereas true thorns are modified stems. Rose prickles ...

Muon tomography, or muography, is the practice of using muons generated by cosmic rays interacting with Earth’s atmosphere to image structures on Earth’s surface, akin to producing an X-ray. In lieu ...
