A Segments from the high resolution CT image. B µ-map based on theoretical values from NIST database [17]. C Theoretical attenuation correction factor (ACFtheoretical) image. \(I_{0}\) is the image with attenuation correction and \(I\) is the image without attenuation correctionBack to article page
