WebThe Hounsfield scale of tissue density is based on two values: air as -1000HU (minimum HU value) and water as 0HU. Density of other tissues is related to this range, usually from -1000 to +1000HU (-1024 to 1024 or 3072 depending on the coding of particular vendor). However, the scale by its the definition is open-ended. WebLater its use evolved to rescaling of digital data for increased contrast and to compensate for exposure technique dissimilitude. ...
