Bug Report

Describe the Bug

Hi Team, I have uploaded the below DICOM file and it is coming as blurry in both v2 and v3 versions. However, I have used some DICOM viewer software like 3D slicer and Horos where it is rendered properly

What steps can we follow to reproduce the bug?

1. Use this anonymized DICOM file and upload it in v2 and v3.
2. Upload the DICOM file https://viewer-dev.ohif.org/local and also in https://v3-demo.ohif.org/local
3. It is rendered blurry

Screenshot on v2

Screenshot on v3

Screenshot on HOROS viewer it is rendered properly there

Issue is with the WASM build for cornerstone Wado image loader v4:

Below are the screenshots for references

I degraded the version of cornerstone-wado-image-loader from 4 to 3.1.2 it worked fine .Below are the screenshots

Chris Hafey suspects it has to do with the code where he added to support of JP2 and J2K files here or may be DICOM is not compliant:

https://github.com/chafey/openjpegjs/blob/master/src/J2KDecoder.hpp#L230

Workaround

• dcm2dcm to generate LEI then drag and drop to view
• Using dcm2dcm to LEI or JPLL results in a valid image
• Using dcm2dcm twice to LEI and then to J2K results in a good image.

https://gdcm.sourceforge.net/html/gdcmconv.html
run
dcm2dcm -jls fuzzy.dcm notFuzzy.dcm
gdcmconv --jpeg IM-0001-0001-0001.dcm not_fuzzy.dcm

cornerstone-wado-image-loader 4.1.2

cornerstone-wado-image-loader 3.1.2
