Your right Sandor. Radiology is constantly adjusting images
(brightness/contrast) to see what’s in their images. It’s not WYSIWYG. We see a
difference in tonality and noise on our DICOM exported Spectralis images. The
Spectralis images are more contrasty and noisy. I don’t know if it’s the
Spectralis DICOM export module or Merge doing something with DICOM image.
Thanks,
Tim

Tim is right on. Get an image directly from the camera & one from Forum &
compare them.
My off the cuff guess would be that there are image adjustments added to the
displayed image that are not being added to the ?DICOM? exported image.
ie Forum is getting a "raw" image file, and the camera is adding on the fly
enhancement.
With our radiology PACS this is a common occurrence - the raw captured
MRI/CT/PET has a much different appearance that an image adjusted to highlight
certain pathology.

Have you compared an image exported directly from the slit lamp with the same
one exported from Forum? That’s what I would do first. Take a look at both of
them in an independent viewer to see if they appear the same or not. And as
Marshall suggested you could look at the histograms for both versions, but just
comparing them subjectively would let you know if Forum is altering them.
Good luck,

Hi all,
Anyone with an BQ900 camera system have an issue with photos showing up in
Forum much darker than shot?
Zeiss and Haag Streit blame the other and we've ruled out monitor calibration.
Any thoughts are appreciated!
