Hounsfieldskálán
Hounsfieldskálán, or the Hounsfield Scale, is a quantitative relative scale of radiodensity used primarily in CT scans. It assigns a numerical value to different tissues based on their X-ray attenuation, which is their ability to absorb X-rays. The scale is named after Sir Godfrey Hounsfield, a British electrical engineer who shared the Nobel Prize in Physiology or Medicine in 1979 for his invention of the CT scanner.
Water is defined as having a Hounsfield Unit (HU) value of 0. Bone, being much denser and
The Hounsfield Scale allows radiologists to differentiate between various tissues and pathologies. For instance, a tumor
