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.

Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations. Logical operations-such as AND, OR and XOR is the fundamental ones, that all the others are derived from.n ALU loads data from input registers, an external Control Unit then tells the ALU what operation to perform on that data, and then the ALU stores its result into an output register. The Control Unit is responsible for moving the processed data between these registers, ALU and memory. 3 people found this useful.
