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.
Best Answer: It means quite a few things: U/L can mean units per liter -- some medical tests are reported in this fashion. Finally, the greek letter Âµ or mu appears occasionally in science. There is, for example, a subatomic particle called the Âµ-meson. It is used in dealing with very small or weak measurements, such as the Âµ-ohmmeter, and in the measurement of wavelengths. I'm sure there are many more, but I think you get the idea. The term Âµ represents (usually) the extremely small or weak.
