• For AAA CT HU mapped to electron density
from user specified (or default) CT-ED curve
– Truncates all HU higher than max in CT ED
curve
– Max electron density in AAA is 15
• CT HU mapped to mass density for Acuros
XB
– From mass density Acuros sets the material
composition of voxels
– Automatic CT to material up to 3g/cm^3,
manual assignment above 3
– Maximum 8g/cm^3 (stainless steel)
