L'échelle des unités de Hounsfield (UH)

Numéro d´article: P2550900

Principle

Depending on the type of CT scanner and the settings, the result of a CT scan of the same material can be different attenuation coefficient (grey-values). In order to make it easier to compare CT data, espe-cially in medicine, the grey-values of a CT scan are often rescaled to a standard scale. Hounsfield units is such a scaling that uses air and water as a calibration material which is regularly used in medicine.

Tasks

  1. Perform a CT scan of the calibration material
  2. Recalculate the results to Hounsfield units

What you can learn about

  • Attenuation coefficient
