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 zero Hounsfield units (HU), while the radiodensity of air at STP is defined as -1000 HU.he Hounsfield scale /ËhaÊnzËfiËld/ or CT numbers, named after Sir Godfrey Newbold Hounsfield, is a quantitative scale for describing radiodensity.
Redefine Cardio â Make traditional strength training your bread and butter and end with cardio. Close out a 40-minute workout session with 5 to 10 minutes of post-workout anaerobic conditioning.
