Scanner spectrale

Le scanner spectral X aussi connu sous l’acronyme SCT (de l'anglais : Spectral Computed Tomography), est une modalité d’imagerie médicale récente qui allie le principe de la tomographie par rayon X (CT) et l’utilisation de plusieurs niveaux d’énergie afin de pouvoir identifier la composition d’une substance d'intérêt. Le scanner spectral permet de réaliser ce qu'on appelle une imagerie spectrale ou encore dite au K-edge des éléments (matériaux). Il existe de nombreu… WebSpectral CT is a way to visualize tissue composition with CT. We can determine the atomic number of the tissues in the body; and if patient has received iodinated contrast, spectral …

Short-wave infrared (SWIR) light is typically defined as light in the 0.9 – 1.7μm wavelength range, but can also be classified from 0.7 – 2.5μm. Since silicon sensors have an upper limit of approximately 1.0μm, SWIR imaging requires unique optical and electronic components capable of performing in the specific SWIR range. havilah ravula https://codexuno.com
