Subject: Display RGB DICOM Series
Reply to author | Forward | Print | Individual message | Show original | Report this message | Find messages by this author
Hi,

I'm using InsightSNAP version 1.6.0-rc2 on Linux and Windows machines.
And I have a RGB DICOM serie (color diffusion tensor images) I'd like
to load. One Windows installation displays this series as expected,
the other installation shows a greyscale version of the images (both
xp machines). What could be a reason for this behaviour? What details
could I check on the "trouble" windows machine? What details would
anybody need in order to help solving the problem? Version 1.5.2
showed the same behaviour...

Thank you for any hint!

Christina Rossmanith

Hi Christina

SNAP has support for loading DTI volumes as RGB. However, they have to be
converted from DICOM to a SNAP-readable MHA format. Gary Zhang has some
information on how to do this, and I'll wait for him to chime in on this
message.

Paul.

what kind of scanner do you get these DICOM images from?

did you mean Linux installation of SNAP here?  what exact procedure  
did you use to load the series into the SNAP?  i.e., can you describe  
the sequence of menu items you have clicked through?

Hi,

the following answeres the mails of both of you...
I think, I've used the term DTI not precisely enough. Those are DICOM images with

0028 0002        2 //          IMG Samples Per Pixel//   3 3
0028 0004        4 // IMG Photometric Interpretation//RGB

They have already been preprocessed and contain the typical color coded principal directions.

The original images are acquired on a Siemens sonata and postprocessed with nICE.

I've loaded the images using the folling mouse clicks:

File -> Open -> RGB image -> Browse (select one of the images of the series which is recognized as DICOM file series) -> next -> next -> next -> finish.

At this point two of three machines display the color coded images as expected, one machine refuses to do so...thus it can't be a problem of the data nor of the way I load it. Could it be a windows system lib being different on the trouble winxp box?

Christina

Hi again after a long while,

my problem is solved  :-)   Finally the "trouble" Windows machine
displayed the RGB images as expected. I've just copied all images
belonging to the RGB series into a separate directory and that already
solved the problem. So it seemed to be a "trouble directory" maybe
containing files with a series UID identical to the UID of the RGB
series...
