Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
Schematic of STEM mode An ultrahigh-vacuum STEM equipped with a 3rd-order spherical aberration corrector Inside the aberration corrector (hexapole-hexapole type). A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM).
Phase-contrast imaging is commonly used in atomic physics to describe a range of techniques for dispersively imaging ultracold atoms. Dispersion is the phenomena of the propagation of electromagnetic fields (light) in matter.
