WebJun 3, 2024 · Uncoagulated blood typically measures 30 to 45 HU. 1, 2 Clotted (or concentrated) blood measures higher at 60 to 100 HU.3 Separated serum plasma is closer to water at 0 to 20 HU. Finally, ascites also has a Hounsfield measurement of around 0 to 20 HU.4. Because the HU of plasma and ascites are in the same range, this technique … WebThis work investigates the changes in Hounsfield units (HUs) which can arise when altering the image reconstruction kernel for planning CT images and the associated changes in dose in the radiotherapy treatment plan if the …

The Hounsfield unit (HU) scale is a linear transformation of the original linear attenuation coefficient measurement into one in which the radiodensity of distilled water at standard pressure and temperature (STP) is defined as 0 Hounsfield units (HU), while the radiodensity of air at STP is … See more The Hounsfield scale , named after Sir Godfrey Hounsfield, is a quantitative scale for describing radiodensity. It is frequently used in CT scans, where its value is also termed CT number.
