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.
An arithmetic-logic unit (ALU) is the part of a computer processor (CPU) that carries out arithmetic and logic operations on the operand s in computer instruction word s. In some processors, the ALU is divided into two units, an arithmetic unit (AU) and a logic unit (LU).Some processors contain more than one AU-for example, one for fixed-point operations and another for floating-point operations.n some processors, the ALU is divided into two units, an arithmetic unit (AU) and a logic unit (LU).
