dicom files

[Jenzermentje]

Hi there

I'm pretty new to labview, so please forgive me if i'm asking a 'silly'question.

I'm building  a labview VI that analyses Rontgenvideos which are in the DICOM fileformat. This DICOM video is a set of frames of rontgenimages, Which I already opened and viewed with the IMAQ create and read files, but the problem is that I only can acces the first frame of the set. My question is, is there a way to acces the different frames in the DICOM file to analyse all of the frames and not only the first frame? Is there someone expereinced with DICOM files in labview? And if yes is there somewhere information available about this DICOM files.

I hope someone can help me with it,

Thx in advance

p.s. I'm working with labview an vision 7.1

Hi Jens,

I did a quick search by did not find much on DICOM and LabVIEW, I did find a site that explains the DICOM format, click here for this link

It looks like the files are basicly a header followed by the images. the IMAQ file functions can only read image files not sequences of images, this is probably the reason why you only see the first Image in the file.

You have several options yiou could look at:

1. Try and find a viewer / editor that can split the DICOM files in to sepparete images and load these in labview.

2. use the labVIEW File I/O functions to split the DICOM file your self and safe them to disk, reopen them to load them in labview.

3. Same as option 3 but try and see if you can do the decoding of the image format in memory, this gives you better performance since you don't need to save and load the image to and from disk.

Hope this helps,

Thanks

Why will u use Labview for DICOM..? There are several tools to access and easily program with DICOM.
