Did you know?
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 0 Hounsfield units (HU), while the radiodensity of air at STP is defined as −1000 HU. … Visa mer The Hounsfield scale , named after Sir Godfrey Hounsfield, is a quantitative scale for describing radiodensity. It is frequently used in CT scans, where its value is also termed CT number.

WebbHounsfield Units (HU) can be used to differentiate between different types of fluid collections based on CT. A seroma usually has a radiodensity value of less than 20 HU, while an uncoagulated hematoma is usually between 30 and 45 HU and a coagulated hematoma is between 60 and 100 HU.
WebbHounsfield worked with Dr James Ambrose, at the nearby neurosurgical unit at Atkinson Morley’s Hospital where the earliest clinical images were created. On 1 October 1971, Ambrose made medical history by carrying out the first CT scan on a live patient, revealing a detailed image of a brain tumour.
