[Gate-users] Standard HU ranges for Abdomen and Brain CT images

[Atiq Ur Rahman]

Dear  experts,
I am trying to read the CT images in Gate. I am successful to read the CT
Image but I am not sure about the precise organ density ranges in HU units
for Abdomen and Brain CT images. Right now, I am trying to implement it
from different online research papers and websites but that may not be a
standard Benchmark.
For example, I am using this file for Abdomen CT:
-1024  -600 Air
-600   -120   Adipose
-120   -90    TissueEquivalent
-90     1     Blood
1      10     Mucus
10     20     Intestine
20     30     Kidney
30    40      Pancreas
40     50     Spleen
50     200    Liver
200    400    SpangyBone
400   3072  SpineBone
 Can anyone point me to some standard material conversion files or
resources with HU ranges?
Looking forward to any feedback.
Regards
Atiq
