CR image is not shown good after convert to JPG

#1 Post by simeon »

Hello,
I have a question about one image from a CR modality.
When I convert it to JPEG, it doesn't look as it must look.
I use following: >dcmj2pnm +oj 0001001A sample.jpg

The left is converted to JPG, on the right how it must look.

Did you already try to specify a more appropriate VOI LUT transformation (e.g. Window Center/Width) than the one stored in the DICOM dataset?

I think it is not related with Windows Center/Width. Because I already try to change them.
Could it related with following?
- Presentation LUT Shape(2050,0020) - INVERSE
- Photometric Interpretation(0028,0004) - MONOCHROME1

No, this has nothing to do with Presentation LUT Shape or Photometric Interpretation: the image is not inverted.

Please try again with the following VOI setting: +Ww 12000 10000
