Web31 de ago. de 2024 · High density substances absorb more x-rays and appear whiter. Low density substances absorb few x-rays and appear darker. The density of each pixel is measured in Hounsfield units (HU), where air is assigned -1000 HU, water is 0 HU and bone is around 500 HU. The range of Hounsfield units included in a study is called the window. WebIn general, the best absorption contrast is obtained at x-ray energies where the absorption is high, meaning a high absorbed dose. Diffraction-enhanced imaging (DEI) derives contrast from absorption, refraction, and extinction. The refraction angle image of DEI visualizes the spatial gradient of the projected electron density of the object.
