Convert dicom file to Image (jpg ir bmp)

[oguhantunes]

Hi,
I am retrieving dicom dose image files from CT Examinations. I get the dicom file successfully.
Now i need to convert it to JPEG ou BMP. I have tried a lot of parameters but it does not work..
I think it should work with this command
dcmj2pnm.exe +Fa +op -O --log-level info dicomfile.dcm jpegfile
But the result is a black image.
Can anyone give me some help?
Information regarding the image:

Hi,

Try one of the VOI LUT options, eg +Wm.

Best regards,
Michael

Since there is a VOI window stored in the DICOM image, you could also select this particular one (with "+Wi 1" or "--use-window 1").

By default, no VOI window / setting is used:

Code: Select all

VOI LUT transformation:

  -W    --no-windowing
          no VOI windowing (default)
