Error displaying some palette color images

[jap1968]

Hello,

I am trying to display ultrasound images using the OHIF viewer (tested with the dockerHub OHIF images, v3.3.4.8766 and v3.3.5.8808)

The instances having the tag Photometric Interpretation (0028,0004) = "PALETTE COLOR" are not properly displayed in OHIF (an error is shown in the browser console, *1) whereas the Cornerstone library is able to display them properly (*2).

(*1) OHIF error message: "ReferenceError: paletteColorCache is not defined"

app.bundle.861010e2bb8a74366fd1.js:35496 The provided colorLUT only provides 0 labels, whereas segmentsPerLabelmap is set to 65535. Autogenerating the rest.

(*2) The image is properly displayed with the Cornerstone library. It has been tested here:
https://rawgit.com/cornerstonejs/cornerstoneWADOImageLoader/master/examples/dicomfile/index.html

The issue has been also reported on the cornerstone-platform topic in Google Groups:
https://groups.google.com/forum/#!topic/cornerstone-platform/5bBkHEVIJ_c
There, you can find a sample DICOM file attached showing this problem.

Congratulations for the great work!

Congratulations!!!

I have just tested this kind of images with OHIF/viewer v3.4.8.9438 and they are properly displayed.
Thanks a lot!
