5 paź 2020 · For CT accuracy and precision should be considered together. For accuracy versus precision, picture a target. On the upper left the shots are scattered, relative to the lower right, so precision and accuracy are low.
20 sie 2019 · The reconstructed CT image is a map of tissue attenuation, and these maps are quantitative owing to the use of a scale called the Hounsfield unit (HU) scale. The scale is named for the inventor of the x-ray CT scanner, Sir Godfrey Hounsfield.
