Reading DICOM images [message #47102]

Hi,

I am trying to process DICOM-images of human lung tissue from a Siemens
Multidetector CT-scanner. The gray-levels should range from -1000 HU to
something like +2000. When I read the image slices ("im =
read_dicom(filename, image_index=1) the grey levels are compressed to
the range 0 ... 255. The situation slightly improves, when I predefine
the variable by "im = fltarr(512,512)". But I still don´t get negative
graylevels.

Who can help?
