Density information is evaluated in Hounsfield units with a scale
from -1024 to 3071. Good initial values for best visibility of brain
tissue and a contrast-enhanced tumor are 0 for the left and 100-
150 for the right parameter.
You cannot adjust all Hounsfield units, but only a subset in a cer-
tain width.
An arbitrary scale from 0 to 255 is used. Within this scale, there
is no direct relationship to any physical density values. Instead,
the values are a function of the parameters defined on the MR
scanner.
