I am able to render '.dcm file' using X.renderer3D() and X.renderer2D(). But the issue is, the image is not displayed completely.

When I manually uncompress and test, it is working fine.

We can try to uncompress and render it at run-time, but it will be an cpu intensive operation right ?

Can any one suggest the right way to achieve the rendering of compressed dicom file.

Advance Thanks for your time.

XTK doesn't support compressed DICOM format. You could hack it in though (https://github.com/xtk/X/blob/viewerjs/io/parserDCM.js#L950-L1023). The main issue is that it requires adding external libraries to XTK.

I would recommend to use AMI that natively supports compressed DICOM format. AMI is still a work in progress but should already allow you to build more advanced apps. Please do not hesitate to submit feedback, pull requests, report bugs, etc.

Try to upload you DICOM images there: http://fnndsc.github.io/ami/#viewers_dicom2D

  • Hi Nicolas ... I am not able to view dicom file over "http://fnndsc.github.io/ami/#viewers_dicom2D" ... screen looks empty. – Hemanth Anakapalle May 12 '16 at 11:20
  • can you share the file(s)? – Nicolas May 12 '16 at 11:22
  • when you say the screen looks empty, you mean after loading the DICOM images right? – Nicolas May 12 '16 at 11:23
  • I couldn't see any attachment option here Nicolas. – Hemanth Anakapalle May 12 '16 at 11:29
  • I have downloaded dicom files from http://www.osirix-viewer.com/datasets/DATA/VOLUMEMERGpickedE.zip ..... unzipped and used one of dicom file. – Hemanth Anakapalle May 12 '16 at 11:29
  • Yes Nicolas ... after loading ... screen looks empty with a rectangle border. – Hemanth Anakapalle May 12 '16 at 11:31
  • You should be able to download now. – Hemanth Anakapalle May 12 '16 at 11:38
  • OK, which folder in particular is not working? I tried a couple one successfully. If you are interested in AMI, just fill a bug report on Github and we can continue the discussion there. https://github.com/FNNDSC/ami/issues/new – Nicolas May 12 '16 at 11:42
